Flying hook
Rayman can catch these hooks by hitting them.
Flying hooks are metallic objects hovering in the air by a propeller. With the Lockjaw, Rayman can grab onto them and reach otherwise inaccessible places. They replace flying rings in Rayman and purple Lums in Rayman 2.
Flying hooks are first encountered in Clearleaf Forest, where Rayman is introduced to the Lockjaw power. They are since seen throughout the rest of the game.
Flying rings are remodeled in the Gameboy Advance version of the game, instead of looking like flying metal rings, they look like metal crowns on top of small semicircular hoops. Rayman can swing on these without the aid of a Laser-Washing Powder, the Lockjaw.
