Flutter

Flutter (Moncho in Japan) is a small butterfly found in Kirby 64: The Crystal Shards that is completely harmless and can't be harmed as well. His wings are white with black edges that just flies around posing no threat to Kirby. Flutter is found in Pop Star Stage 1, as well as Ripple Star Stage 1, which is a remake of Pop Star Stage 1 with different enemies, a different mini-boss battle, a different Crystal Shard location, and a different case holding a Crystal Shard itself.
