• Alias: Shellmouth, Ocean Guardian, Ocean Protector

Template:Monster InfoBoxThe Shellmouth are hostile creatures that can be found in the Frontier. They are often compared to a Whapper and the Forest Guardian. They are usually seen at Coral Bay. They also appear in the Otherworld Tower.

In appearance, it is a hulking hunchback-like creature that patrols a specific zone. It wields a fallen tree, just like the Forest Guardian. Its main colors are grey, pale, and blue. It has a perplexed expression as implied by its drop, Perplexed Shellmouth.

There is one attack that the Shellmouth will unleash upon unwary players. The guardian will swing its weapon, attempting to land a hit on the player.
