Jack-in-the-box (object)

A Jack-in-the-Box is a kind of toy found in Shy Guy's Toy Box during the game Paper Mario. When Mario ground pounded one, the box would shoot flying up, making Mario jump really high. When the box opened, a fake clown sticking his toungue out would appear. The box would then close, hiding the clown again. Jack-in-the-Boxes are very similar to Trampolines.
