The Sparky Twins (voiced by Mel Giedroyc and Sue Perkins): A debatably greenish blue Little Robot couple with different coloured belly buttons. The twins are almost identical, are full of energy, love dancing, and doing practical jokes on other robots. Sparky One has a pink spot on her belly and Sparky Two has a yellow spot on her belly. They are able to communicate over distances by exchanging electrical rays through the antennae on their heads, and their catch phrase is Gimmie Three, Sparkee! They live in a pair of speakers by an old record turntable. The Sparky Twins often hang out with Tiny (thinking that he might be their favourite Little Robot).
