The secondary beach is completely ice-effect, making it very difficult to find hidden treasure.
Touching the icey water will cause you to be stuck sliding around until you happen to come to a complete stop. This also can be observed by walking off the top circle of the fountain (which also is playing the water noise)
This bug has been around ever since the Hallowe’en update, since the fountain was slippery in that one spot back then (for some reason)
The workaround to being slippery is to use the Little Crusaders ghost morph, as that morph does not experience the effects of friction.
