PopCap are going head to head with the X-Factor this Christmas. Crazy Dave aka. Cray-Z is the talent behind Wabby Wabbo. It's available to buy through iTunes (opens in new tab) now. Purchases registered between December 18 and December 24 will count towards Wabby Wabbo's Christmas chart rankings. PopCap mention that "approximately 55p of each 79p purchase" will go to the Concern Worldwide charity.
PopCap point out that Wabby Wabbo "is believed to be the first hip-hop single ever released to feature a yodelling solo by a Yeti zombie." It may also be the first hip-hop single ever released to contain just five real words ("heeey, gonna eat your braains"), and is probably the first to be performed by an animated character wearing a saucepan on his head. The official music video is above, which means you've probably heard it by now. What do you think?
