To gain all the sparkle, you'll have to explore every rectangular edge of the map. There are shards of shine hidden in secret alcoves, between rollers, and on hard-to-reach edges. Then you'll have to go up and down the entire stage with a wrench - or sprint through an obstacle course in record time. However, you will easily find the Bowser blocks. They are literally right next to the entrance.

Roiling Roller Isle 100% Completion Guide | All the cat shines and the cat parts
Chat Shine # 1: Like on Mount Magmeow, the Bowser blocks are right at the start of the level. Just look to the right of the entrance to the cat's door at the level, on the large gray tower.
Cat Piece # 1: The first Shine Shard is located in the gap of the big blue scroll at the start of the level. It sounds treacherous, but there is actually an invisible platform underneath.
Cat Piece # 2: The second Shine Shard is at the back of the blue roller - the first lava-covered roller in the level. If you don't see it, just wait for it to spin all around.
Cat Piece # 3: After getting off the blue scroll, you will reach an area filled with stacked Goombas. The third coin is on Goomba's biggest stack!
Cat Piece # 4: On the green roller, take a Bob-Bomb and crush the stone blocks in the blue roller in front.
Cat Piece # 5: The last piece is on the second green roll. It's on the end of a long ledge, so a raccoon costume will come in handy here.
Chat Shine # 2: Collect the 5 cat coins to earn this shard.
Chat Shine # 3: Reach the top of the level to find this shard. There are several Raccoon Suit power-ups in the large stacks of bonus blocks. These make this level much easier.
Chat Shine # 4: Come back to this level later to find an Obstacle Course button. Activating it creates a series of platforms - reach the end within 20 seconds to get the Shine. This one is very simple, and a raccoon costume or a cat costume will make it much easier.
Chat Shine # 5: The latest Cat Shine is a major challenge. Reach the very top of the level, then bring the key back to the entrance. The Raccoon Suit power-up makes this so much easier. Pick one up from the Bob-Bomb spawner and you can then descend safely.
