Kirby 64: The Crystal Shards: Part 12: Aqua Star 3~ (All 3 Shards)
This level is a mishmash of beaches, coral fields, caves, and the occasional forest again.
There are two barricades here:
The first one I break through is a green and brown wall, which means you need Stone/Cutter to break through, but then the Crystal Shard is too high up for Kirby's float to reach.
Stone/Cutter random turns Kirby into a rock sculpture of one of his friends from Dream Land 3, and each of them move differently. You want the Rick sculpture because he can climb walls. Use that that to get the Shard.
The barricade before this is instead a green and black, which means you need Bomb/Cutter instead. This will give Kirby exploding shuriken, and is basically the closest you will get to Ninja Kirby in this game. I had to use a different level to prepare for this.
