The Jumbo Dungbomb was a product which could be brought at Zonko's Joke Shop. It was a variant of the original Dungbomb product. It was considered very rare, which was joked about by Bilton Bilmes when he claimed the price for such a product was over one million Galleons.
The product was kept under thirty-seven separate locks in an offactory-controlled environment, since it was a very special variant. In the 1986–1987 school year, there was only one Jumbo Dungbomb in Hogsmeade, which was purchased by Jacob's sibling for pranking Merula Snyde.
