Fuzzball

Fuzzballs are purple creatures that appear in Luigi's Mansion: Dark Moon. They are only found in the Secret Mine's Chalet, and look similar to Toothberries.

These creatures cannot damage Luigi on contact or via attacks. Instead, they chase Luigi around and get in the way of the Poltergust 5000. If Luigi picks one up using it, he can shoot it around the room and stun it for a short time. They appear at the end of mission D-1: Cold Case.

There are also Gold Fuzzballs that drop gold bars and bills when thrown. These turn into the normal purple versions after being thrown around three times.
