FAQ
How many purple coins are in Seaside Kingdom?
Seaside Kingdom has 100 regional coins. This route covers every coin exactly once across 33 clusters.
What do Seaside Kingdom purple coins look like?
They are shell-shaped purple regional coins used in this kingdom’s Crazy Cap shop.
Should I finish the story before collecting every coin?
Defeat Mollusque-Lanceur first. The cleared fountains and unlocked checkpoints make the island-to-island cleanup much faster.
Which Seaside Kingdom purple coins are easiest to miss?
The most common misses are the turnback alcove at the end of the Lighthouse tunnel, the hole in the northern island, the Ocean-Bottom Maze set and the Back Canyon alcoves.
Do I need a Gushen for Seaside Kingdom purple coins?
Yes. A Gushen is the intended way to reach the high southwest group, and it also makes several water-to-cliff transitions safer.
Do I need all purple coins to finish Super Mario Odyssey?
No. Regional coins are optional, but collecting all of them lets you buy every kingdom-specific Crazy Cap item.
Do Seaside Kingdom purple coins respawn?
No. Every regional coin remains collected on that save file and permanently increases the kingdom counter.
