Infinity Jump (also called Continuous Jump) refers to the ability of certain characters in the Kirby series to jump in the air over and over indefinitely. The infinity jump technique can be performed by Helpers in Kirby Super Star (Ultra), by Bandana Waddle Dee in Kirby's Return to Dream Land, and by most Friends in Kirby Star Allies. The technique is specifically for the purpose of keeping up with characters who can fly, such as Kirby, King Dedede and Meta Knight. It is debatable if this technique is canon to the storyline, or just a gameplay element to make these characters more viable.
In addition to these characters, Kirby can experience this technique himself while using the Wheelie Rider ability, when possessing an appropriate enemy using the Ghost ability, or when Piggybacking on a friend who can use it.
