Big Chungus is an overweight Buggs Bunny, with immense cosmic reality warping power, the only way to fend off big chungus is to sacrifice a bunny on Easter morning, Big Chungus is the only existing entity that can destroy and kill shaggy, but Big Chungus has been neutralized by the media for being irrelevant and being a dead meme, but he is coming back, slowly and quietly, his birth was between late 2018 and early 2019.
