Scarfy (also known as Scarfly) is an enemy character that appears in several games in the Kirby series. At first glance, Scarfy looks like an orange, floating, round ball, with a cute face, and pointy, cat-like ears-- but if Kirby tries to inhale Scarfy, it turns into a ghastly, one-eyed creature with fangs, and starts to chase after Kirby, exploding on contact (it will also explode if Kirby avoids it for a few seconds). Scarfy is vulnerable to all other attacks.
In Kirby Super Star, Kirby 64: The Crystal Shards, and Kirby Super Star Ultra, some Scarfies turn into their one-eyed forms while Kirby's back is turned on them.
Scarfy is one of the few Kirby series enemies that cannot be inhaled. However, using the Copy ability (from Kirby Super Star and its remake) on a Scarfy results in Kirby obtaining the Crash ability.
In more recent games, Scarfies do not explode (in addition to Kirby being able to inhale them with Throw in Nightmare in Dreamland, Amazing Mirror, and Squeak Squad).
In Kirby Super Star Ultra, When Kirby's Grab (Beam, Fighter, Ninja, Bomb, Yo-Yo, Jet, Parasol, Ice, Suplex) some ready to catch that made a Scarfy explode and then they damage enemies, killing enemies, damaged bosses.
