In M.U.G.E.N, a bonus game from the flash game has been made by Dark Ruler. Instead of Castle Cat, the player can use characters in his roster for go in the German countryside. The enemies do little damage and the player can progress without too much trouble with normal moves, hypers moves are not required.

However, this bonus game has some problems, such as some non-cohesive elements in the background (cut mountains, black lines on the landscape and a "floating" tree).
