BellBot is a Power Sphere wielded by Cattus in order to protect it from evil aliens. It gives Cattus Size Enlargement power.
Due to its tiny size, BellBot is tied around Cattus' collar. It usually faces backwards to the public to fool outsiders to think that it is only a bell. Moreover, it rings like a bell when it's moved.
BellBot speaks with a toddler-like voice.
