Kirby in Sonic The Hedgehog
Not unlike what you can do at Kirby games, you can swallow almost everything here. From enemies to monitors and rings.
An innovative and really funny idea. This isn't just a sprites mod, but you can do a lot with Kirby besides just running and jumping.
...it can't be forgotten how funny is to see him jumping in the same style of Sonic.
The project was developed by Lone Devil, but it also features sprites from Drshnaps and Dr-Luxcario among the ingenious Hcktrox programming. Be sure to check it out!
