Remember when Plants vs Zombies‘ Crazy Dave released a hip-hop video on YouTube? Well now you can buy the track with proceeds from the sale going towards charity.

The single, “Wabby Wabbo,” is now available on iTunes for $0.99. And Popcap says that all the proceeds from sales of the song between December 15-24 will be donated to Concern Worldwide, a charity organization that fights poverty throughout the more impoverished nations on the world.

The video for the song has amassed more than half a million views on YouTube. You can purchase the extended iTunes version here.
