Biography
When Luigi enters the room, he finds Clem sleeping on the top and tries to make as less noise as possible to not wake him up. However, Luigi accidentally steps on a rubber duck that produces a sound that quickly wakes Clem up. He becomes angered upon seeing Luigi and activates a valve that fills the entire room with water, hoping that Luigi drowns in the process. Unfortunately for him, Luigi manages to get into an rubber duck inner tube to protect himself, so Clem gets in another one to fight Luigi personally using his hand fan. In battle, Clem will try to get closer to Luigi to attack him with the fan, causing him damage. Luigi has to use the Poltergust to suck which makes the inner tube move contrary to the direction he is aiming.

After a few attempts, Clem will make a spin attack that causes him to go dizzy. When he is vacuumed, the inner tube will be stuck in the suction and will instead cause it to deflate sending Clem to fly around the room until he lands on the floor. While Clem is unconscious, Luigi must go up to the floor and vacuum Clem before he tries to use another inner tube to go to the water. If he fails to do so, Clem will reappear using another inner tube to fight Luigi in the water. Now, Clem will throw a bomb in the middle of the pool, limiting Luigi's space to move.

After being defeated, Clem will struggle to free himself before being finally sucked in, while humorously releasing several rubber duckies in addition to the tenth floor's elevator button which falls into the pool, requiring Luigi to drain the reservoir to get the button.
