Arena

This article is about the sub-game in Kirby's Adventure and Kirby: Nightmare in Dream Land. For the similarly titled sub-game introduced in Kirby Super Star, see The Arena. For the game mode in Kirby Battle Royale, see Battle Arena.

Mid-bosses	Mr. Frosty, Grand Wheelie, Bugzzy, Bonkers, Fire Lion

The Arena is a bonus room found in the lobby in various levels of Kirby's Adventure and its remake, it is a large gladiatorial-style amphitheater where Kirby can fight a pre-selected mid-boss. Kirby can get a Maxim Tomato after defeating the mid-boss and can also eat it for its ability. This idea would later be redone into a sub-game in Kirby Super Star (as well as its remake), Kirby's Return to Dream Land, Kirby: Triple Deluxe and Kirby: Planet Robobot, in which Kirby fights all of the main game's bosses in a random order with limited recovery items, while the player's time is recorded.

Unlike sub-game bonus rooms, these Arenas can be entered and challenged as many times as the player wishes, much like Museums.
