BoBoiBoy (2011)

S1E8 Justice Does Not Sleep!

After emerging from the game, Papa Zola chose his biggest admirer, Gopal, to be his apprentice. However, things took a turn when Yaya offered him a biscuit, causing him to faint. Meanwhile, the Sleep Monster, along with Probe and Adu Du, paid a visit to Tok Aba's home, lulling both Tok Aba and Ochobot into slumber. This left Ying and Yaya ensnared in the monster's dream bubbles. To rescue them, Papa Zola, Gopal, and BoBoiBoy decided to enter these dream bubbles, but found themselves in a game of checkers where the Sleep Monster used the others as game pieces.
