Minecraft Dungeons:Turtle

The Turtle is a passive mob that was added in the Hidden Depths DLC that also acts as an objective mob.

Behavior
Turtles tend to swim around aimlessly, unlike base game turtles, they have a unique idle behavior where they lie on their shells and float motionless, as well as being capable of doing a flip, as seen in the caged turtles in the Radiant Ravine.
