Bot's Pets who only appeared in The Kitty Rescue.
Bot has an ant farm with five ants inside that he keeps as pets. Each one of the ants has his/her own name: Bob, Joe Bob, Billy Bob, Bobby Bob, and Sparky. The ants all have a high-voice except for Sparky who has deep-voice.
Each of the ants is black in a different shade to tell them apart from another.
