Lockup

Lockup is an enemy who is found in Treasure Trove Cove in Banjo-Kazooie. It resembles a treasure chest to match the world's theme. Although it is immobile and cannot be killed, it is fairly large and hollow inside and can be jumped into only when its lid is opened. Its lid, however, is lined with spiky teeth and has a pattern of opening and closing every few seconds.

Banjo and Kazooie need to do a Flap Flip jump (hold + ) to get into the chest to find the various "treasures" it holds, one of which is a Jiggy.
