Sir Slippys look like frogs- except they only have two feet. Sir Slippys are moderately-common to rare enemies that tend to hop or swim toward Kirby as their method of attack. Sir Slippy gives no ability when swallowed.
Sir Slippy is a frog head with an orange, pink or blue top with a yellow, light pink or green belly. He has two small eyes and small, straight-positioned feet.
Sir Slippy debuted in 1993 video game Kirby's Adventure, he is first encountered early in the game during Vegetable Valley with latter-mentioned attacks.
Sir Slippy is found on the top stage of Whispy Woods Land. He mostly hops around on a small platform toward the top of the screen. Behind him is an item - usually an apple or Invincible Candy. If Kirby defeats all the Cappys, a black Warp Star will appear behind him. Kirby must hit the Warp Star quickly if he wants get to Whispy Woods, because the star will disappear after a moment. Hitting Sir Slippy will earn the player 3000 points.
Sir Slippy's behavior hasn't changed since Kirby's Adventure.
