Rusty (voiced by Morwenna Banks): A feminine and sensitive Little Robot who gets nervous at times. She has a red dress which is made of painted rusty metal and wears a funnel-like hat on top of her head. She lives in an old, rusty bucket, and she constantly has new ideas on how to improve and decorate it. She's very impulsive and accidentally prone, though, and tense situations or anything that causes her to get overexcited can make her overheat and release puffs of steam from her funnel. She has a childish crush on Sporty.
Rusty is also the only female whose favourite colour is blue
