Crazy Dave, who you might remember as Plants vs. Zombies' power-up purveyor, can't actually speak English. But that hasn't stopped him from producing a rap song, apparently, which PopCap is now selling for 99 cents on iTunes, in order to raise some money for charity this holiday season. The single, which features "Cray-Z" murmuring over a bombastic beat, has already picked up over 600,000 views on YouTube, and PopCap says all profits on the song's sale are going to Concern Worldwide.

What's Concern do with its nonprofit funds? Helps grow plants, of course. How else are we going to take on the coming zombie bobsled threat?
