Seaweed

Seaweed is an uncommon item only found in the Underground Jungle's Jungle Shrine and is used to summon a pet turtle.

Usage
Used via left clicking the item on your hotbar, it spawns a Turtle. It can also be used by pressing whichever button is linked to "Quick Buff". The turtle is used purely for aesthetics and does nothing beneficial. You can rarely fish some seaweed in the corruption.
