Chapter 3: Seaside is split into six creature levels. Jump straight to the level you are cleaning up. Each link shows the Flower count and the main thing to check in that route.

Weewoo Smiley Flower Locations

Weewoo is a music-based Seaside route. Carry the Weewoo to the right landmarks and use its music to wake up hidden Flower triggers.

Ouchin Smiley Flower Locations

Ouchin mixes ship-deck checks with a hidden underwater platform. Bring eggs and watch for high clouds above the mast.

Casterway Smiley Flower Locations

Casterway asks you to fish in specific water and mud spots. If a Flower is not visible, use the Casterway from a better angle.

Bafloonder Smiley Flower Locations

Bafloonder is an underwater movement route. Inflated dashes break crates, reach waterfalls and open hidden seabed paths.

Snurfboard Smiley Flower Locations

Snurfboard hides Flowers behind wave jumps and underwater checks. Stay on the board long enough to inspect both the shipwreck and the far-right route.

Nep-Enut Smiley Flower Locations

Nep-Enut revolves around throwing droplets and combining Nep-Enuts. The cave behind the waterfall is especially easy to miss.
