Bitefrost

A Bitefrost is an enemy encountered in Super Mario Odyssey, appearing in both the Snow Kingdom and the Luncheon Kingdom. They are in the shape of a large pillar, with the top of their bodies being their eyes and two sets of blocky teeth. Bitefrosts hide underground, awaiting for Mario to stand directly above them, and they will rise up above ground, carrying Mario with them. They will wait a few seconds before gnawing their teeth as an attack. Mario can know beforehand when a Bitefrost is below him, as an outline of their faces will be present on the ground (similar to the Sandmaarghs from Super Mario 3D Land). Mario can use Bitefrosts to his advantage to reach higher up places, though he will quickly have to jump elsewhere before the Bitefrosts shut their teeth on him.
