K.S.-n-Kickin is a game created for Kinder Surprise as a giveaway in 1999. The game is based on Gubble 2, featuring the same levels as the original game but with redone artwork for the backgrounds, items, and enemies, which were replaced with Kinder Surprise toys, and replacing the main character with the Kinder Surprise mascot Kinderino. The game was offered in exchange for Kinder Egg wrappers which were sent to Ferrero.

Yes, description was taken from MobyGames but since I was the one that wrote that one as well, I think that's ok. As you would expect, this isn't for sale anymore but you can find it on abandonware sites. It really is basically just a Gubble 2 reskin.
