During every episode that Dedede Academy appears in, a monster is always there to occupy the school. Basically, the academy's purpose is to teach the Cappy children their lessons. Like any school, it also has rules (with the #1 rule of respecting its owner, builder, and formerly principal, Dedede himself), though the rules are not like any normal school. The school was built and rebuilt on at least three different occasions throughout the series, but naturally, in the end, it was blown up every time by Kirby whenever he destroyed the monster occupying the school.
