The First Annual Cartoon Convention

Mako looked around in awe at all the other cartoon characters around him. He had no clue that there were this many cartoons, let alone this many that liked conventions. Mako was waiting at the entrance for Korra, Bolin, and Asami.

Team Avatar hadn't met in a while. Ever since Kuvira's defeat, they had all gone their separate ways. Mako and Korra had gotten back together and were keeping in touch. As for Bolin and Asami, Bolin had started to help rebuild the Pro-Bending arena while Asami was manufacturing Future Industries's new product, "Interactive Movers AKA The Nuktuk video games". Mako kept scanning the crowd for his friends. He thought that the Realm Crystal had opened a portal to Ninjago to the Cartoon Convention right next to the spirit portal. He spotted Bolin running towards him.

"Hey bro! Long time no see!" Bolin exclaimed, slapping his older brother on the back.

"Nice to see you too," he replied.

"Can we go check out the convention?" pleaded Bolin.

"Fine" sighed Mako. He had wanted for Korra and Asami to arrive, but he didn't want to disappoint Bolin. The brothers strolled over to the "The Legend Of Korra" section. A huge replica of the Pro-Bending arena instantly caught his eye he saw Korra at the front of the entrance to the arena using her avatar powers to give people bending so they could take a crack at the Pro-Bending arena against someone else in line. Mako and Bolin lined up. Mako continued to scan the crowd looking for Asami. He spotted Asami in the crowd watching the Pro-Bending matches. She walked over to Mako and Bolin waving back.

"Oh! Hey Asami you scared me!" Bolin exclaimed.

"How have you two been?" She asked.

"Great except for the incident where Bolin ordered so much of his favorite dumplings that he made us broke" Mako replied.

"Oh come on! I had to work at Cabbage Corp because of that! I've learned my lesson!"

"Speaking of dumplings I bought some dumplings for Bolin on my way here," she said, handing over a steaming package. The instant she pulled it out Bolin's tongue lolled out. She handed them to Bolin who immediately gobbled them up.

"Who slow down!" Mako scolded.

"Sorry. I have a dumpling problem" Bolin replied bowing his head in shame.

"C'mon, we're first in line for the pro-bending" Mako told Bolin.

The two brothers stepped onto the arena. Their opponents were Leshawna and Harold from the TV show "Total Drama Island".

The memories all came flooding back from the pro-bending arena, Bolin throwing up, Equalists attacking the arena and meeting Korra. Mako's flashback came to a halt when the arena flipped over. Asami, Korra, Mako, Bolin, Harold, and Leshawna went tumbling down a chute under the arena.
