Flying ring
A flying ring is an object in the original game which allows Rayman to reach inaccessible places. Once he gets the Grappling Fist from Betilla the Fairy, he simply has to punch them and then, Rayman will swing on an invisible rope, materialized by a sparkling line. Some of them, recognisable by their reddish colour and their black eye, start falling as soon as Rayman hits them.
In Rayman 2, they are replaced by purple lums, and in Rayman 3, by flying hooks.
