"Toci, do you know Papá and Agatha being best friends?" Marigold asked as she, her family, and the Sánchezes went to Toci's place in Aztlan.

"Not as well as the Sánchezes, but I did play a part in their friendship story." Toci replied. "Xibalba and Agatha were like partners and they always work together as a great team, but it was not last. It all happened when Aggie, and her team, the Imaginary teams, gone into an advance training, like gone into a real fight, but just pretending, of course. And with these new technology devices in this century, Aggie and her friends decided to go on virtual training. The place, the obstacles, even virtual enemies are real to fight, and even cause pain sometimes. It is said that each member, including Aggie, should fight, and tested how they fight. The most important rule of fight, according to Agatha, that shouldn't be reckless and never use anger in fighting. Your parents are the rookies of the team. La Muerte has great fighting skills and determination, but as for Xibalba..."

Flashback

Xibalba was in the virtual training room. The place was like the Land of the Forgotten, and he fought the virtual Forgotten Beasts and the Forgotten souls who were against him. He used the moves that Aggie taught him when they discussed Lesson number 1 to 5. Aggie and the I teams were watching him the control room.

"You were right, Aggie. This Xibalba god is really good." Numbuh 5 (from Codename: Kids Next Door) said.

"Told ya." Aggie winked. "He might be a dark god in the Land of the Forgotten, but he still got the guts to fight with heart, brain, patience, and determination. He was once a knight before."

"That explains the armor." Skipper (from Penguins of Madagascar) chuckled.

Xibalba fought with his staff and sword. He caused no accidents, but he was really strong and undaunted. He might can be fight in real life with the I teams if he ever train right in this virtual training.

Aggie has observing Xibalba's moves. He's good, but not good enough if he ever had a weakness. Everybody has weakness, including Aggie herself. He might be 'The Trickster', but he has a heart and feelings. "Guys, remember that during your training here, I put each of your weaknesses while fighting?"

"Well, yeah, you did." Pooh (from Winnie the Pooh) said.

"What's your point?" Tigger (from Winnie the Pooh) bounced around the room.

"What if we should increase Xibalba's danger level, and put his weaknesses in his virtual training." Aggie suggested.

"I don't know about that, Agatha." La Muerte said in worry. "We all know Xibalba's weaknesses; Me... and Agatha."

Aggie was shock as she froze for a second, then turned to La Muerte. "Me? Why am I one of Xibalba's weaknesses? I thought it was only you."

"Agatha, you're Xibalba's only mortal friends." The sugar goddess explained. "He hates humans all his life, until you prove to him that not all humans are the same of what he thinks. And you're the example."

"Well, we should give this just one try."

"But—"

"I just want to help Xibalba for his training."

La Muerte sighed. She wanted to do anything for her husband. She knew what was best for him, and she wanted to do what was best for him, too. "Alright. I'm in."

"Aggie nodded as she commanded her friends before she and La Muerte headed to the door to enter the virtual training room. "Guys, increase the level."

Maurice and his guardian, Mac (from Penguins of Madagascar) turned the danger level from level 7 to level 9, making this level harder.

La Muerte and Aggie entered the virtual room as Aggie made a force field to protect themselves just in case if ever they get hit.

When Xibalba took down the (virtual) Forgotten Beasts, he noticed his wife and best friend inside a force field in the training room. "Mi amor? Agatha? What are you doing here?"

"It's part of your training, Xibalba." Aggie explained. "Now since you noticed us, you have to stay focus on your fighting!"

"But you two will get hurt!"

"Don't worry, I made a force field to protect us. Just focus on your training, okay?"

Xibalba still felt worry for his wife and friend that they might get hurt, but he had to stay focus on the training. After fighting a dozen Forgotten Beats, he was a little reckless that he accidentally pushed the Forgotten Beast with so much energy against the rock, making the rock shattered and cracked into a million pieces, and sent to the air.

As the shattered rocks started to fall, a bigger shattered rock fell towards La Muerte and Aggie. Aggie used some of her energy to increase the strength of her force field, but the rock just 'smashed' them.

Xibalba saw that, and he gasped in horror. He thought his wife and friend were smashed, all because of him. This made him angry at himself and his stupid training as he attacked all of his opponents, secretly using his Sword of Seven Sins. Unbeknownst to him, La Muerte and Aggie were actually behind the large that almost smashed them, and watched in horror of Xibalba used his sword to attack, which it was not suppose to be part of his training.

"Xibalba, no! Don't use that!" Aggie tried to warn him, but he didn't hear him. Then, she turned up to her friends in the control room. "Guys! Decrease the level!"

"We're trying, Aggie!" Private (from Penguins of Madagascar) yelled as he and the others tried to turn the danger level to decrease, but it got stuck. "But Xibalba's strong and powerful energy trapped him in this level!"

Feeling guilty, hurt, and depressed, Xibalba thought he can't protect his loved one of being so reckless either both in his training or in real life. When he distracted, he didn't noticed that the Virtual Forgotten Beasts attacked him, scratching, stomped, and threw him against giant rocks, hurting his back and body.

Seeing Xibalba was already hurt, La Muerte teleported back to the control room, and immediately hammered the emergency stop button.

While his enemies attacked him, Xibalba ignored the pain, and still felt guilty he can't protect his love one if he was so reckless. He felt the attack of his enemies suddenly, and the entire room faded back to white empty room.

"Aggie, we have to take Xibalba to Toci." La Muerte said. "Open the portal, while I go get him."

"Got it." Aggie nodded as she used her dimensional remote control to open the portal back to

At the Land of the Forgotten, Xibalba rested in his chambers with bandages around his arm and chest, while Toci told La Muerte, and Aggie that he'll be fine as long that he take a long rest.

Aggie decided to talk to Xibalba about what happened to him in the training room. As she entered, she looked worry at his friend got injured, and bandages wrapped around his chest. He was not sleeping; he's still awake, but not in a mood of looking at her.

"Hey, buddy, are you okay?" She asked but the god didn't answer her. Aggie sighed desperately. "Xibalba, you shouldn't do that back there. You were quite reckless, and you are very angry when you're fighting."

Xibalba immediately sat up in depressed as he glared his friend/mentor. "None of this would ever happen if you and La Muerte hadn't entered the room."

"I was only trying to help. Your weaknesses are one of your opponents to make you stronger and smarter when you are in a battle, but I see when you took down a Forgotten Beast on a rock, your recklessness almost killed us, and when you though your wife and I got smashed by a huge rick, you use anger to attack! I told you never to use anger!"

"When I thought you and La Muerte got smashed, I thought I can't protect you two."

"And don't think that way! That's what I trained you before. And we were behind a rock before you attack your components"

"Well, Agatha, your training got me nothing but trouble."

"I was only trying to help you, Xibalba. You and your wife are the rookies of the team. I just want you two be advance like the rest of us."

"What do you mean I'm the rookie? I'm a god; a high-levelled."

"But you and La Muerte are new here. In the training room earlier, La Muerte has the heart and determination, and you are reckless, used anger in fighting, and used the Sword of Seven sins! You shouldn't use that in training! Those are two of my lesson I taught you!"

Xibalba can't take it anymore as he hammered a desk besides him with desperate and anger. "Agatha, this training of yours caused me trouble, lots of accidents, and your lessons; they give me nothing but pain!"

Aggie's anger was replaced by shock and sadness. "What are you saying?"

There was a little silent until Xibalba spoke out. "I quit!"

Aggie's mood changed to anger again as her pupils changed to red. "You can't quit! You'd just started!"

"No, I mean, I quit being your student! You can't have my back, Agatha!"

"Are you saying that... you don't need me anymore?" Aggie started to shed a tear as Xibalba stared at her. "I thought we're friends."

"Well, friends shouldn't let their friends get hurt." Xibalba said, putting on his gloves. "Like what you did earlier. I don't need your wisdom anymore, Agatha! It makes no sense!"

Aggie's tears formed on her eyes, almost going to fall before Aggie wiped them. She could feel her heart break into too when Xibalba said those horrible words. "But, Xibalba, I was only trying to—"

"Well, stop trying!" He yelled loudly. "Your stupid ideas of helping nearly killed me! Look at me now. I'm injured! Now, I'm going to stay in bed for a week!"

She could feel her heart break into two when Xibalba said those horrible words, and sniffed as hot tears rolled down her cheeks and her pupils remained red. "So why don't you sell me, and buy a rabbit instead?"

Realized his mentor started to insult him, Xibalba insulted her back. "At least a rabbit behave better than you!"

"Go ahead, then you'll be happy, because it'll be smarter than me, too!" She yelled as she went out of the room, and opened a green portal by her dimensional remote control.

"And quieter!" The tar god roared as he got out of his room to watch his friend go.

"You'll like it 'cause it's stinky like you!" She entered the portal.

"GET OUT OF MY REALM!"

"I'M ALREADY OUT OF YOUR REALM!"

Xibalba growled one more time as he watched the portal disappeared, until La Muerte smacked him on his shoulder. "OW! What?"

"What did you do?!" La Muerte glared at him.

"I didn't do anything! She started it!"

"Xibalba, I know you're mad, but Agatha was only trying to help."

"Oh, now you sounded just like her. Why do you agree with her?"

"Because I know what's best for you, and so do her. Now, you hurt her feelings."

"Well, good." Xibalba slouched at the wall, but he suddenly realized La Muerte was right. Aggie did care for him, and now, he hurt her. "Oh, me and my big mouth. I'll tell her I'm sorry tomorrow."

So then, he waited, and waited, and waited.

It's been 8 months since Aggie left the Land of the Forgotten. Xibalba already missed her and her parties. He tried to call her on his phone she gave him, but she didn't answer. One day, when he checked Aggie's room, everything in the room was rocky once again, all of her things are gone, and most of all; what Xibalba found on the rocky bed was Aggie's wand staff that he gave to her. The wand staff's head was a sitting penguin, and its handle is black-and-white stripes. It is clear that Aggie left for sure, and never came back.

Feeling guilty, guiltier than before, Xibalba he has gone way too far of hurting aggie like that. She's just only trying to help, and he blew it. This is worse that telling her that he tried to get rid of her. He thought before that he lose he's new best friend before, but later then, she returned, and it started all over again, but this time, Aggie never came back to the Land of the Forgotten again.

"Balby, are you okay?" La Muerte entered the room where Xibalba was.

Xibalba turned around to face his wife, and showed Aggie's wand staff. "She's not coming back, mi amor. She's not, all because of me."

When her husband sat on the edge of the rocky bed, La Muerte sat beside him and touched his gloved hand. "It's not your fault, my love."

"Was it? Agatha worked so hard to make me a better fighter and friend, and I didn't listen." The tar god started to sob. "This is all my fault! I went all monster on her! Nicholas was right."

"Don't listen to what Nicholas said about you, my love. He is not like Agatha. She likes you being yourself, just like I did."

"But how I yelled at her like that, made her change her mind about me. Now, I lost my best friend, twice, and I lost my second best human friend!"

When Xibalba started to cry, La Muerte placed her head on his shoulder, and hugged him gently. "Don't worry, she'll be back. I promise."

End of Flashback

After listening to the sad story, Kyroc, Clara, and Hugo held onto their Marigold's waist, feeling sad about what happened to their grandfather and his friend as little tears formed in their eyes. When Marigold comforted both of her sad children and half-brother, Juan Carlos rubbed his wife's shoulder, feeling shivered in shock about his father-in-law's story with his mortal friend. Camazok kneeled on one knee to comfort little Algner, also reacted the same as how Kyroc, Clara, and Hugo reacted. Zipacna rubbed his forehead, feeling depressed about his little brother, and adoptive little 'sister'

"I can't believe hermanito and Agatha just fought like that, and never got a chance to make up!" He said. "No wonder he and La Muerte never told us about any of this."

"These things were never easy since their friendship broke." Toci said.

"And it's hard to know when it is a good time." Anita added, still knitting on his wheelchair.

"It seems to me that now's as good a time as any." Marigold said.

"To talk to Papi and Aunt Agatha." Hugo added as he and his family left Toci's place, leaving Toci and the Sánchez family a little worry.
