I'm trying to remember the name of a game I played a long time ago (10-15 years.) It was a sort of platform puzzle type game where you controlled a small ball of fuzz . It could change colours to give itself a different ability. I think blue could swim and green could swing. At least one of the levels was on a stone like substance. I have spent a good while trying to find it to no avail, so any help would be appreciated.

Bingo! Cheers, I have been furiously googling vairents of furball platformer ability and colour for far too long.
