At base, Optimus was walking around. Unbeknownst to him, the others were planning a surprise party for him. It was his birthday today!

Optimus would be 32 years old. His surrogate daughter was planning the party. "Okay so. What does Optimus like?" Miko asked. "He likes the colors blue and red." Summer replied. "He also likes flames. I saw him looking at different flame tattoos on his computer." Ratchet added.

"He's never been painted before. And he needs a new paint job." Arcee stated. Just then, Summer thought of something. "What if we surprise him with a new paint job? It could be our big gift to him." Summer suggested.

Bumblebee and Smokescreen looked dejected. "But we already made gifts for Optimus." Bee stated, sadly. "Don't worry, Bee and Smokey. You can give Optimus your gifts too." Wheeljack reassured.

"Name everything you made for Optimus people!" Miko exclaimed, careful so Optimus didn't hear. "No Miko. That would ruin the surprise basically." Jack scolded.

"The whole idea if a surprise party, us keeping the person and gifts at bay until the party. That being said, we keep everyone's gifts a secret until the party." Summer agreed. Just then, they heard Optimus leave base for some fresh air.

"Okay, now that he's gone, let's get decorating. Also, Magnus. You'll need to cover Optimus' eyes so he doesn't see anything." Raf stated. Ultra Magnus nodded in acknowledgement.

An hour later, the whole base was covered in decorations. Suddenly, "Where are you taking me, Ultra Magnus?" Optimus asked. Magnus had to resist the urge to smile or chuckle.

"You'll see, Optimus. Just stop trying to move my hands." Magnus reassured. Optimus obeyed and stopped when Magnus did. "You may remove your hands now, Magnus." Summer instructed.

When he could see, Optimus was speechless. There was blue and red decorations with flames around the base. Finally he managed to reach his voice again.

"What... what is this for?" Optimus asked. "We knew that it was your birthday today so, we decorated for it. Do you like it?" Jack asked. "I love it. Thank you. I've never celebrated anything before." Optimus replied.

"Everyone helped, including Magnus, Ironhide, Ratchet. We all pitched in for this." Raf stated. "You all can come out now! He's not mad!" Miko yelled.

Out of a room came everyone. Wheeljack, Ironhide, Bumblebee, Smokescreen, Bulkhead, Arcee, Jazz, Sideswipe, Sunstreaker and finally Ratchet. Optimus was shocked at seeing the work his soldiers had done.

"Happy birthday, Dad." Summer smiled. Optimus smiled back at his daughter. "Thank you all for this." Optimus thanked. "No problem, Optimus." Jazz reassured.

"Present time!" Summer announced.

Here is the list:
Wheeljack and Arcee- diary
Jazz &Ironhide- new computer
Ratchet: No wrench hitting. JK, JK! He gave Optimus new books to read.
The Twins: Made a new blanket for Optimus. Quite good, I add
Bee and Smokey: Made cards for Optimus.
Ultra Magnus: Made Optimus a new comm-link thingy majigy.
Summer: Painted Optimus but added a mixture of blue and red flames. (Like his Bay version)
The humans: also made cards, but birthday cards.

Optimus couldn't have been happier than what he was right now.
