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.
- BellBot looks like a tiny yellow bell, hence, its name "BellBot".
- She is the second Power Sphere to appear in BoBoiBoy Galaxy.
- As seen from a poster of BoBoiBoy Galaxy Cards, BellBot has legs.
- She can also shrink down a Power Sphere (as it was shown at Episode 22).
