Turtles seem to get on an empty boat and be unable to move unless beaten by the player. They even move with the boat if the player uses it.

The first time it happened, I hit the turtle with a sword and it scaped, but the second time I tried to hit it with my hand but only the boat received the hit. Destroying the boat frees the turtle.
