Main article: Jr. Pac-Man (game)
Yum-Yum appears in the cutscenes of Jr. Pac-Man. Her and Junior fell in love with each other, but Blinky does not allow them to be together. After catching Jr. Pac-Man giving Yum-Yum a balloon, Blinky chased him down, trying to kill him; luckily the two escaped together, surrounded by hearts.
Yum-Yum looks like a smaller version of Blinky, but with what appears to be either a bow or rabbit ears on her head. In some console versions, it appears to be another propeller beanie like Junior's.
