After defeating the first room of robot mini-bosses, the children come upon a hidden room where they find pets waiting for them, a dog and a frog. The dog runs to the boy and the frog hops happily over to the girl. They feel an instant friendship with the animals. Then they decide to head to the next room together, wondering what lies ahead.
The four friends see a larger robot; however, before they can make a plan of how to defeat this monster as a team, the frog and dog try to defeat the monster by themselves.
The pets, feeling invincible, start to attack the robot on their own. However, they are overpowered, and the robot starts to launch sushi out of its stomach, stopping them in the process.
