Heatoise

The Heatoise first appears as a mini-boss in the Fire Temple in Spirit Tracks. Usually accompanied by a (or multiple) Spark(s), when hit or provoked the Heatoise will put its limbs and head into its shell and spin towards Link. The object to defeating a Heatoise without the bow and arrows is to cause the Heatoise to spin into a Spark, which stuns the Heatoise during which time Link can kill it.

The Heatoise is similar in appearance to the Snapper from Majora's Mask.
