Chilly reappears in Sonic Speedball RPG II: The Coming of Chaos! and this time Kirby appears in the game.
Chilly appears as both a rare enemy and an ability for Kirby. He will pop out of a ? Block and try to attack any of the characters. If Kirby inhales the enemy or if Meta Knight gains his ability with the sword, they will get the Ice ability. This does the same thing that an Ice Flower does.
