Numboo is a recurring enemy in Pac-Pix. Numboo is technically three separate ghosts, each with a different number on it’s belly, with the numbers always ranging only from one-three. To eat Numboo, you must eat each of the 3 ghosts separately according to the numbers on each of their bellies. You must consume each ghost in ascending order, starting from ghost 1, then ghost 2, then ghost 3.
