Course No. 21

Course No. 21 is the second course of Stove Canyon in Wario Land: Super Mario Land 3. The majority of this level is set over a sea of lava with several small platforms Wario must jump across.

Layout
At the start of the level, Wario crosses three bridges with Pirate Gooms and a Demon Bat, the third of which has collapsing floor boards that can cause him to drop into the lava below. Once on the other side with the block containing a Dragon Pot, Wario encounters a long stretch of lava with several platforms he must jump along to cross it. At the end is a small platform that sinks into the lava, then rises up shortly after. Past the lava is a wide bridge whose path is blocked by more enemies and breakable blocks, followed by the door to the checkpoint.

Just after the halfway point, there are two blocks on the ground between two walls containing hearts that can only be hit with Dragon Wario's fire. Past the blocks, Wario must quickly jump along three consecutive sinking platforms before they lower him into the lava towards more stable platforms. After crossing the lava, Wario reaches a pair of collapsing bridges, each occupied by a Pirate Goom with an invisible block containing a heart suspended above. More sinking platforms over lava lie ahead that lead Wario to a ledge with the door to the final room. In the middle of the room is a small lava pit with a Bōtsu leaping out of it, while the goal door is found on the right side.
