Seaweed is a pet-summoning item which summons a Turtle pet that follows the player, like other pets. It lasts indefinitely and does not attack enemies nor take damage, and is purely for aesthetics. Seaweed can rarely be found in the Underground Jungle's Jungle Shrines or Living Mahogany Trees. On the Desktop version, Console version, and Mobile version, it can also be found in Jungle Crates and Bramble Crates.
- The Turtle pet will use a propeller to fly to the player when out of reach.
- On the Mobile version and version, there used to be a coding error where the Seaweed obtained from fishing would have the description of the pet-summoning Seaweed.
- The pet turtle is a reference to Tank, a pet tortoise from My Little Pony: Friendship is Magic. This has long been suspected by members of the community, and on May 17th, 2021, Redigit confirmed this to be the case.
