Pi'illodium is a boss that appears in Mario & Luigi: Dream Team. As stated by Prince Dreambert, Pi'illodium is a defense weapon used by ancient Pi'illo folk to guard certain objects. Pi'illodium is accidentally awakened by Mario after he hammered it out of the way when he and the others tried to place the Ultibed on Pi'illo Temple in Somnom Woods.
Pi'illodium is similar in appearance to Eyepi'illos that also appear in Somnom Woods. Pi'illodium is large in size and is mainly golden in color. It also has an odd-shaped face and red eyes.
Pi'illodium is a heavy hitter in battle. It always summons smaller versions of itself to attack. Pi'illodium can also use a laser disc attack that can hurt Mario and Luigi. Beware as before Pi'illodium is defeated, it will self-destruct and Mario and Luigi must defeat it in forty seconds.
The Bros. Attacks Bomb Derby and Slingsniper are very effective in this fight. It should be noted that after Pi'illodium's wings are destroyed, it's power and defense will decrease dramatically and it will be unable to move for a couple of turns. As for the self-destruct, using a well-aimed Slingsniper should finish it in one hit. Also, Taunt Balls can be used on the enemies in the background to bring them forward and can be destroyed to prevent the wing healing.
