|“||Torpedoes with spikes on their sides, Rockns shoot out of walls when Kirby passes by. Jump or duck to avoid them, and be on your way.”|

Rockn is a dark blue rocket with two blue, metal cylinders for a body. It has white eyes with black pupils, a yellow nose, four propellers between the cylinders and four more on its bottom. Unlike Pedo, it lives on land.
Rockn makes its only appearance in this game. It appears to be a rocket; it moves forward, exploding if it hits anything. They appear to be shot out of cannons, as they continually reappear, even when defeated. Rockn gives the Bomb ability when inhaled.
- Rockn's name is very similar to the Japanese name of Pedo (Gyokkun), as well as the Japanese name of Skud (Mikkun).
- Pedo, another enemy that appeared in Kirby 64: The Crystal Shards, is extremely similar to Rockn. The only differences between them are that Pedo is aqua green while Rockn is blue, and that Rockn has eight silver propellers. Pedo has only four.
