At a store named Fast N' Easy, Mordecai, Rigby, Y/N, Thomas and Pops are buying a slushy to take photos of their faces after drinking the slushy. Mordecai and Rigby open the door. "Sluuushyyyyyy!" Mordecai pays for the slushy and Pops takes the slushy. Rigby holds the camera. "Reaadyyy?" He askd. "Let's do thiiiyuuuuus!" Mordecai said. He drinks the slushy while the 3 cheers "Brain Freeze!" repeatedly

Mordecai then makes a weird face and takes a photo. Rigby drinks the slushy and also made a weird face after being "brain frozen" and taken a photo. Pops drinks the slushy then kneels to the ground and reached his head then laughs. "Ahhahahahaaa. Brain freeze!" He also makes a weird face then takes a photo. "Haha, here I go!" Thomas drinks the slushy but didn't make any weird face like the others did. The slushy didn't "brain froze" him. He then laughs and takes a photo. Mordecai, Rigby, Y/N, and Pops look at the photo for a bit then laugh. "Dude Thomas, you call this a brain freeze face?" Mordecai asked. "Weak-saaaauce!" Rigby said.

"I agree. Jolly weak show." Pops said, and The 5 of them laugh. "What about you, Y/N? You go next." Rigby said. "Okay." She takes a sip, and Rigby looks at the picture. "Ha! You didn't freeze either!" He said. "Really?" Y/N asked curiously, then looks at the photo. "Okay." Thomas pauses for a bit. "Wait, wait, wait!" He opens the top of the cup and chugs the whole slushy but nothing happens and he laughs.

"Dude! What is wrong with you?" Rigby asked. "Dudes, dudes! I got this, I got this." Thomas goes inside the store and Y/N follows. "Hey man, what's the coolest slushy you got?" Thomas asked. "Uhh, that would be the Cool Cubed. It's imported from the Arctic and contains real glaciers. But I strongly recommend that you reconsider-" Thomas cuts him off. "I'll take it! Big Swig size." He said. The cashier gets the big swig cup, puts on goggles, gloves and puts the slushy to standard to "Cool-Cubed". "Go easy on this, bro." The cashier said. "Uh Thomas, are you sure this is a good idea?" Y/N asked worriedly. "Of course. Don't worry, I'll be fine. You want one too?" Thomas asked her. "No thanks..." she said, a bit worriedly.

Back at the outside of "Fast N' Easy", Mordecai, Rigby and Pops are saying "Chug! Chug! Chug!" repeatedly while Rigby is holding the camera for the picture as Y/N watches, still a little worried. "Okay. Okay. Here it goes." While Thomas drinks it, ice goes up to the tip of the straw and then he sips it while the other three keep repeating. When he finished, nothing happened and he is calm again. "Lame." Rigby said. Thomas suddenly got a "brain freeze" face but is frozen still by the cool cubed slushy. "Thomas?" Y/N asked worriedly. "Ah dude!" Rigby said. "Take the picture! Take the picture!" Mordecai said. Rigby takes the picture and the three of them laugh,

but Y/N was still concerned. "Dude, this is gold!" Mordecai said. "Thomas, Y/N, check it out!" Thomas doesn't reply then falls down and Y/N panics. "Thomas!" She quickly runs over to him. Rigby chuckles while taking more pictures of Thomas's "brain freeze" face. "Now that's a brain freeze. Alright, come on." The three walk away but notice Y/N desperately trying to wake up Thomas. "Thomas? Thomas? Thomas, wake up!" She shouted. But he doesn't come back to normal. "Y/N what's wrong?" Mordecai asked. "Guys, he's not waking up!" She shouted. They all get worried and look at each other and approach the goat duo. "Thomas!" Y/N shakes him, then feels his forehead and quickly pulls away. "Ah! He's freezing!" She shouted. "Whoa, Y/N calm down!" Mordecai said, grabbing her right arm, but she yanks it away.

"Calm down?! Thomas still hasn't turned back to normal yet! What if he's dead?!" She asked, and tears began to leak out of her eyes. "Whoa, whoa! He's not dead, Y/N! He's just still in a brain freeze!" Rigby said. "Are they supposed to last this long?!" Y/N asked. "I don't know!" Mordecai said. Y/N holds Thomas' arms. "What do we do?" Pops asked. "We have to unfreeze him." Mordecai said. "Yeah, no duh!" Y/N said furiously. "You guys better fix this!" She growled. In the restroom, Mordecai opens the shower curtain, and Rigby turns a shower nob to hot. Then, Y/N puts Thomas in the shower but, Thomas leans to the wall but Mordecai puts him back correctly. "Hot towel." Y/N said. Pops feels the heat of the towel. "Ooh! Ooh! Ooh!" He gives Y/N the towel and she puts it on Thomas's head.

"Check him! Check him!" Rigby said. Y/N checks, but Thomas is still frozen. "Ugh! This isn't working!" She shouted. Later at Skip's home, Skips opens the door and they showed up for his help. "Bring him in. Hmm...Yeah I've seen brain freezes before, but not as bad as this." Skips nods. "This is beyond my medical knowledge. Luckily, I know a guy who can help. He's been treating Pop's family for generations." He said. "Oh, of course! Dr. Henry!" Pops said. "Lets call him." Mordecai said. Dr. Henry's car flies down to the front of Skip's house. Pops opens the door and it's Dr. Henry. "Oh, Dr. Henry! So good to see you!" Pops said. "Hello Pops. How's that old pinkie of yours?" He asked. "Pop-notch!" Pops chuckles.

Dr. Henry checks Thomas's ear which is approved to be filtered with ice. "Hmm. So, he drank a slushy, you said." He said. "Yes." Y/N said. "Did you make him drink it?" Dr. Henry asked, and Y/N glares at Mordecai and Rigby and they gulp. "Uhh...maybe?" Dr. Henry wasn't convinced. "Yeah, we did." Rigby said. "Can I see the cup?" Y/N gives the cup to Dr. Henry. "Hmm." He makes a sound with his tongue. "Cool Cubed, Big swig size. This is quite a pickle. Well, I got some good news and bad news. The good news is that the core of Thomas's brain isn't completely frozen yet which means, there's still a chance to throughout." Dr. Henry said. "Okay. What's the bad news?" Y/N asked worriedly. "The bad news is that the Cool Cubed slushy is still very active, it's working its way to the brain core as we speak. If it gets there, Thomas's brain will stay frozen. Forever!" The four them gasp in horror. "What?!" Y/N asked.

"What do we do?!" Mordecai said. "Simple. I just shrink you to little tiny people then you go inside of Thomas and you can stop the cool cubed slushy before it reaches the core. It's a dangerous procedure but, it's the only way to save him. Any volunteers?" Dr. Henry asked. "I'll go." Y/N said immediately. "Wait, we'e coming with you." Y/N turned to the blue jay. "We got Thomas into this mess,

so we're gonna get the mess out of him!" He was unsure if that made sense. "I think." He said. "Okey dokey! Let's get started!" Dr. Henry gets the shrinking machine out of his suit case. "The shrinking won't last forever, so take this alarm." Rigby puts on the alarm to his wrist. "When it goes off, you will grow back to normal size so move quick! You'll also need this." He holds a small speck. "It's just a speck!" Rigby said. "Shh. Its what's inside the speck that counts. It contains all the equipment to thaw the core including a transporter, which would bring you back, just push the red button and poof! You'll be back safe and sound." He puts the speck in the tube. "Now. In you go." Dr. Henry said.

"Hmm! Hmm! Hmm! Hmm! Hmm!" The trio go in the shrinking machine. Dr. Henry presses the buttons to make them shrink. "Oh! I forgot to tell you. Shrinking is extremely painful." Dr. Henry shouted. "What?!" The trio shouted. The trio scream from their regular voices into a miniature voice and go into the tube. "Remember, just five minutes to save Thomas and get out." He puts them in Thomas's head. "Oh, Dr. Henry, what will happen if they don't make it in time?" Pops askd. "Well, it's hard to say Pops, worst comes to worst, they'll just take very long naps!" Dr. Henry said.

"Ooh! I love long naps!" Pops chucked. "That means they're going to die." Dr. Henry whispers to Skips. The trio are now on the insides of Thomas, swimming as they look for the core. Later, they swim to the surface and breathe and get out of the stream and finally make it out to breathe and everything is filled with snow in a blizzard. "It's freezing!" Mordecai said. "I can't feel my fingers!" Rigby shouted. "Wait a minute, Y/N, you don't seem cold." Mordecai said, and her eyes widen a little. "Uh..." she said. "Yeah, how come you aren't cold? It's freezing in here!" Rigby said. "Um... well..." she said nervously. They suddenly hear a goat sound.

"Dude, what's that?" Rigby asked. A goat appears. "It's Thomas!" Y/N said. "Mor-de-cai. Rig-by. Y / N." He suddenly has the voice of Thomas. Mordecai and Rigby scream. "Whoa guys, chill. It's just Thomas." Y/N said. "No way, dude. How can you be Thomas if we're inside your...uh. His head." Mordecai said. "I'm Thomas' Consciousness. Of course I'm in my own head." Thomas said. "Hmm. I guess that makes sense." The area rumbles and

Y/N, Mordecai and Rigby scream. "Uhh, what was that?" Y/N asked. "The cool is making the brain unstable. It can't hold much longer like this." Thomas said. "Do you know where the brain core is?" Y/N askd. "Yeah, it's over there. Take a look." Thomas said. Y/N took out a pair of binoculars and gave it to Rigby to let him see where the brain core is. Rigby sees it surrounded by an igloo, then sees a group of huskies gliding the sled while, he also sees the Cool Cubed and his translator going for the core. "Freeze! Freeze!" Cool Cube said. "Mush! Mush!" The Translator said. "Dude! The Cool Cubed is almost at the core! What are we gonna do!?" Rigby asked.

"We're gonna stop that slushy!" Y/N said. All of them go in the shed where they see all the supplies they need. "Dr. Henry makes one heck of a house call!" Rigby said. "This might be the transporter to take us back. It's too big to carry, we have to come back for it. Time to suit up." Mordecai said. They put on jackets, get matches, bow and arrows and more of the supplies then put it in the vehicle and then got in. "Let's blow torch this sickle stand." Y/N said.

They leave the shed, then the Cool Cubed and his translator are still going to the core. "Freeze! Freeze!" Cool Cube notices them coming. "Freeze! Freeze! Freeze! Freeze!" He shouted. "Hmm..." he still keeps on going. "Hah!" The translator said. "Yeah! We got him!" Rigby said. They see a glacier and they try to avoid it. The three scream as more glaciers rise. They try to avoid the risen glaciers. Later, they are all close to each other but then Mordecai turns the switch to go farther then the Cool Cubed. "Freeze! Freeze!" Cool Cubed shimmers then zaps the right caterpillar track of the snow vehicle then the other three fall off of it. "Freeze!" Cool Cubed and his translator come closer to them.

"What's your problem man!?" Rigby asked. "Leave Thomas alone!" Y/N shouted. "Freeze! Freeze! Freeze! Freeze!" He said. "I am the coldest slushy in the world. I have a reputation to appalled, which means no area of this brain goes unfrozen!" The translator said "Freeze! Freeze!" Cool Cubed said. "Now you die!" Cool Cubed shimmers again and fires another beam. "No!" Thomas's consciousness jumps in the way of the freeze beam and gets hit. His whole body but head is covered in ice. "Freeze! Freeze! (translation) Finish him!" Cool Cubed shouted. "Hahahahaha!" The translator laughs evilly. "NO!" Y/N moves Thomas's consciousness out of the way when the translator was about to spear him but ended up making a crack of the ground making him fall all the way down but, the Cool Cubed still went for the core. "He's getting away!" She shouted. "Hurry. Go, go!" Thomas shouted. "But, we can't just leave you here!" Mordecai shouted.

"Just. Stop the Cool Cubed." The ice begins to go all over his face. "Thomas!" Y/N said worriedly. Mordecai puts a hand on her shoulder for comfort. "Come on!" He said. They all start running along to the core. "Freeze! Freeze! Freeze! Freeze! Freeze!" He begins to climb on the igloo where the core is. "Freeze! Freeze! Freeze! Freeze! Freeze!" Y/N, Mordecai and Rigby pant while they climb and when the Cool Cubed was already in the top of the igloo, he saw the core and was about to go in until Rigby pulled him in the leg. "Freeze! Freeze- " Rigby grunts. "Hold him up while I find the core!" Y/N shouted. Rigby goes on Cool Cubed. "Stay away from his brain hole." He punches Cool Cubed repeatedly. "You slush bag!

When Y/N saw the core too, she was about to put out the dynamite with the fire matches until the Cool Cubed noticed and pushed her to make the supplies fall in without warming the core up but fell close to the core. "Ugh..." Y/N said. Cool Cubed goes in to freeze the core. "Freeeze!!" He shouted. "He's gonna freeze the core!" Rigby shouted. "Freeeze!!!" The Cool cubed is about to freeze it but, Y/N gets ready to warm it up by getting a bow and arrow. "Dude! What are you doing?!" Rigby asked. "Doctor's orders." Y/N shoots the arrow to the dynamite directly when the whole igloo starts to explode beating the Cool Cubed. When everything falls apart in the igloo, Y/N, Mordecai and Rigby fall down while screaming but, when they barely fall. Rigby starts to blink when the 5 minutes were up and then Rigby's hand starts to grow. "Aah! Uh, dudes?" He asked. "We gotta get to the transporter!" Mordecai said. The trio

start to run while their jackets start to rip apart while they were growing more and more. All of the snow and blizzard was going away then all of a sudden, they both saw exactly the same spot where they first saw the transporter. "Find the Transporter!" As he was said, Y/N looks quickly for the transporter on the melted water. "Dude?!" Y/N sees the transporter and gets it. "I got it! I got it!" She said. "Press it! Press it!" Rigby said.

Y/N still grows too while she attempts to press the button while they leave back to the real world. "Thomas?" She asked. Thomas's eyes start to blink then he's finally awake with his normal face and he gasps. "Whoa! How did I do?! How did I do?!" He asked. "Uh Thomas, your brain was totally frozen. You almost died." Y/N said. "Whoa, Really?" He asked. "Yeah, but we were injected in your body and saved you! Check out your pho-to!" Rigby said, and Thomas makes a face of disgust, and Y/N giggles. "Your brain freeze photo was the best of us all Thomas!" Pops said. "Yeah it did!" Mordecai said. Everyone laughs while Thomas exams the photo of his brain freeze face. "Hahaha haha! Oh. Oww. Ow." Thomas said. "Are you okay, Thomas?" Y/N asked. "Yeah..."
