The Krabby Patty That Ate Bikini Bottom - S8.E25

While looking for spare change, Mr. Krabs notices an over-sized soybean at Sandy's Treedome. Mr. Krabs is interested in what could have enlarged the plant, and Sandy revealed an experimental growth formula, which Mr. Krabs steals out of sight. At the Krusty Krab, he uses the growth formula on a Krabby Patty, but it keeps on growing until chaos erupts.
