Pet Turtle

The Pet Turtle is a Pet summoned by using Seaweed, which is found in Ivy Chests, which are found in Jungle Shrines in the Underground Jungle.

Trivia

 * The turtle is in fact actually a tortoise (the first has fins where the latter has feet).
 * The fact that the turtle pet uses a propeller to fly to the player is most likely a reference to My Little Pony: Friendship is Magic. Where a pet tortoise named Tank similarly uses a propeller to fly.
