Degout[from internal data] is an enemy the debuted in Kirby's Return to Dream Land. It can be considered cousins with the Scarfy and the Mumbies, but is distinct from them in its robotic appearance and high HP.
Kirby's Return to Dream Land
Degout is found within the Egg Engines and Dangerous Dinner levels in Halcandra and in stages in Popstar on Extra Mode. It looks very similar to Mumbies, though it bears a robotic shell rather than bandages. It cannot be inhaled. There are two types of Degout. The standard Degout has a gray coloration, and will either remain passive until attacked, or attempt to pursue Kirby while his back is turned, much like a Boo from the Mario games. The second type has a red coloration, and is known as a Hunter Degout, which attacks any character holding a Key, similar to a Hunter Scarfy.
New Challenge Stages
Kirby: Triple Deluxe
Degout appears briefly in Kirby: Triple Deluxe and bears a slightly brighter metallic shell and light yellow eyes as opposed to the old orange ones. Unlike in previous appearances, Degout is never passive, and will always attempt to pursue Kirby or King Dedede. While Hunter Scarfy does appear in this game, Hunter Degout does not, which may be the reason why Degouts are more aggressive than their appearance in Kirby's Return to Dream Land.
Kirby: Planet Robobot
Degout appears late into the game, not being seen until stage 3 of Rhythm Route. It bears its yellow eye from Triple Deluxe, but is generally more passive, like its Return to Dream Land incarnation.
