Glaseado's fearsome reputation to climbers does not only come from Crabominable or other fully evolved ice pokemon; one must also evade the unique hazard of Cetoddle rolling downhill. Cetoddle are a happy, playful species for whom sliding down mountaintops is the world's most entertaining game; they are also large, round cetaceans who slide with more than enough force to knock someone off a mountain trail.

Cetoddle accumulate snow as they slide, which, together with their color, gives the impression of giant snowballs. Bouncy pokemon with a tough, icy exterior, Cetoddle themselves invariably recover from their falls and collisions, even should the snow fail to insulate them; if one rolls all the way off the mountain, the only loss experienced is the time spent returning to the summit. The climb back up appears a Sisyphean task, for starting their roll is not easily controlled, but the Cetoddle sliding from the peak testify to their eventual success.

It is widely believed that the walk back up is the real reason these pokemon evolved this form of play; their known relatives are fully aquatic, and even a perfect slide (itself a nigh-impossible feat) still requires a hike back to the top to do it all over again. It takes time and practice to balance one's self on land – a fact lost on most terrestrial creatures, who are better adapted and do so throughout early childhood – and all the more to do so on snow and ice. A falling Cetoddle is playful, unless it hits you; a Cetitan fall is a miniature earthquake or avalanche, leaving injuries comparable to a beached Wailord. Knowing how to slide also means knowing how not to slide, and Cetitan fall far less often than one might ordinarily expect for a pokemon of their immense size and weight.
