The fourth part of the 2012 Custard Covered Girls special, filmed using the world famous TopGunge Studios and the antique GungeTankGirls Gunge Tank! This special features the fourth gunging and was produced and filmed by CustardCoveredGirls!

We are down to just three girls and to determine which two go through to the final, we are going to play `Buzz`. Our girls take it in turns to count up from 1, but when they come across a number divisable by 7 or that has a 7 in it, they must say `buzz` instead. First girl to lose two lives gets gunged!
