For the first time in recorded history, the "heavyweights of gross" have combined forces in a massive merchandising blitz that pits the Madballs against the Garbage Pail Kids! And, as part of this blitz, Dynamite presents the comic book cross-over of these iconic 80s brands! For over three decades, Madballs and GPK have both been known as the "grossest of the gross", co-ruling counterculture with their pun-heavy names and subversive humor. This all-new limited series event features the first time these two delightfully crude forces have ever met! This issue: ""BAND SLAMMED"", ""PYRAMID SCHEME"" (a Puzzle page!), ""MAD(BALL) SCIENCE"", and ""MAKE YOUR OWN MADBALL"" (an activity page!) Written by Sholly Fisch, each issue features three incredible covers: Legendary Garbage Pail Kids artist Joe Simko, series artist Jason Crosby and a special trading card team-up cover, created specially for this momentous meeting of the (depraved) minds!
