Kayo is a rather small bunny! Xe just came out of space to investigate human behaviour, and xey just figured the best way to do it in fact was to become a beloved little pet! As xey figured Xey just liked the bunnies of earth the best for the cute and dorky behaviour and people even liking them for it. Xe just decided this would be xyr earthly form! 

Xey are pretty perky and a happy natured bunny. Liking the companionship Xey get form their 'pet human'.
The pet human will not see Xyr spacy colours, but rather a 'normal' bunny with odd green eyes and a funny looking white spot!
