Wario encounters Awabō in the optional level Captured Syrup! after traversing the level area leading to his chamber. When he enters the chamber, he'll see Captain Syrup enclosed in a bubble, slowly flying upwards. Awabō will then appear and challenge Wario. Wario needs needs to jump on Awabō's head three times to defeat him and clear the level. After each hit, the boss will create a duplicate of himself, trying to confuse Wario. If he touches the enemy, Awabō will trap him and teleport him to the top of the room. The battle has to be restarted if this happens. After Wario wins the battle, he will effortlessly defeat Captain Syrup and get his treasures back.
