Octoboos enemies that first appear in Super Mario Galaxy 2. They are a cross between a Boo and an Octoomba. They have the same attack as the Circling Boo Buddies from Super Mario World. They appear in the galaxies Haunty Halls Galaxy and Boo Moon Galaxy. They are primarily undefeatable and therefore must be avoided.


They have ghostly tails, blue antennae, and a spout. They also have glowing, yellow eyes.
