Lurker

Lurkers (generically referred to by PRIMA as moving bumps) are objects found in the Sand Kingdom, the Snow Kingdom, and the Seaside Kingdom in Super Mario Odyssey. They are glowing bumps in the floor that can be defeated with a Ground Pound. Lurkers can be temporarily stunned by throwing Cappy at them. When one is defeated, a Power Moon appears. In total, there are three Lurkers.

Lurkers in the Sand Kingdom and the Snow Kingdom are found in the boss battle arena after the boss is defeated. The one in the Seaside Kingdom is found in the sub-area underwater.
