Tok Aba recaps the events of the previous episode and this one starts off with him being as equally surprised as everyone that Papa Zola appeared in the living room. Gopal is ecstatic to meet him, and Papa Zola sees the truth in Gopal's claim that he is his number one fan. Meanwhile on Adu Du's spaceship, the villain of the video game, the Sleep Monster, was also unleashed from the game. After proving that he was in charge, Adu Du tells the monster about BoBoiBoy so he can get the monster to destroy him.
Yaya accidentally incapacitates Papa Zola with her biscuit she offered him since he was hungry. Then Adu Du calls from outside BoBoiBoy's house. A fight between the Kid Heroes and the Sleep Monster ensues. Large bubbles blown by the monster trap all the good guys except for Gopal and BoBoiBoy in deep sleep. Gopal turns some bubbles into banana fritters before BoBoiBoy blows the rest of them back at the enemies, trapping them in sleep as well.
The two of them wake up Papa Zola and explain what happened. The bubbles, according to Papa Zola, were the way into the Sleep Monster's Dream World, and the only way to free their friends was to defeat the monster in his own realm. With Papa Zola's help, Gopal reverts some banana fritter balls into bubbles again and enter the Dream World, which looks very alike to the TV show's setting. BoBoiBoy's friends are still asleep and the Sleep Monster's turned into a giant. Papa Zola magnifies his own size to fight him, but BoBoiBoy and Gopal convince them to settle things by different means: a game of checkers. The Sleep Monster allows this with one condition: all of them have to be the checker pieces.
This episode provides examples of:
- Cliffhanger: The episode ends with everyone trapped in the Dream World, the unconscious superheroes trapped as the pieces of a checkers game on top of a building for the giant Sleep Monster and Papa Zola to play.
- Literal-Minded: Adu Du announces from outside BoBoiBoy's house that he has a present for BoBoiBoy. When Probe understands that the Sleep Monster is that present, he wraps up the monster offscreen to put in a present box.
- You, Get Me Coffee: When Adu Du gives the newcomer monster the mission to destroy BoBoiBoy, Probe asks if he has a mission. Adu Du replies yes - to go and fetch him a drink.Probe: Aw... just that? What am I, a waiter?
