MC Avalanche is the DJ at the ski resort that replaced Stan's rustic winter campground in "Epic Powder Dump". He uses his equipment to set off avalanches to punctuate his name, but has trouble sometimes scratching records due to wearing mittens.
When Stan gets buried in an avalanche of his own making, Roger tries to organize a search party for the family, but can only succeed when he puts the emphasis on party. However, the drunken group is not only useless in finding Stan, but they knock over MC Avalanche's jury rigged DJ booth and bury him under his equipment. After the family locates and rescue Stan, he decides to join in the party, but with MC Avalanche out of action, suggests they need to call an ambulance.
MC Avalanche is voiced by Craig Robinson.
