Cheery Tomato is a robotic sidekick to Albearto during the latter's musical performances, in which she played an electric guitar. When Albearto was accidentally brought to life by Donatello, he used his tentacle-like wires to also bring Cheery Tomato to life so she could fight the Turtles. She attacked Donatello in the ball pit, only to be electrocuted by him. As she began to melt, she detonated herself, blowing up the ball pit.
Another Cheery was seen alongside an Alberto in Al Be Back, prior to the Albearto from War and Pizza taking control of that Albearto.
