Ceiling Surprise

Ceiling Surprise is a white ghost with a freaky smile that hides on the ceiling, and drops down to freak out Luigi in Luigi's Mansion. It is generally coupled with another common ghost, usually Bowling Ghosts. Ceiling Surprises are extremely weak with zero HP, and always drop a ten- or twenty-HP restoring Heart when captured. It also goes away when sprayed by an element. Ceiling Surprises will keep returning in Area 2 and 3 until the area is complete. They have sub-species called Purple Bombers.

Trivia

 * The inspiration for the Ceiling Surprise could be the Boo Blah.
 * If one defeats a Ceiling Surprise with an element, it does not expel a heart.
