Messyproduct's skin
A Super Smash Bros. Ultimate Crazy Frog skin has been made by user Messyproduct, with help from GTPunk and LukeTheLPSWolf. The skin itself can be used to replace Wario in the character roster, and even features a surprise appearance from Gummibär. When the Warioman final smash is activated, instead of Crazy Frog eating Wario's garlic, he gobbles up Gummibär and powers up into his B-Boy Outfit. This skin also comes with Axel F included to swap out F-Zero's "Car Select" track. There are two versions of the Crazy Frog skin currently available, one censored and the other uncensored. Both skins can be found and downloaded here.
