Spheal
The Clap Pokémon
Type: Ice/Water
Official Registration #: 363
Entry: Despite being a large, seal-like pokémon, spheal are not particularly good swimmers. Instead, they travel from place to place by either rolling their ball-like bodies or by using their rubbery flesh to bounce from spot to spot. Due to their adorable appearance and largely docile nature, tamed spheal can sometimes be mistaken for toys. It is possible to distinguish spheal from rubber balls by bouncing them and determining which one claps; spheal will clap in response to either pleasure or excitement, including excitement of the negative sort.
Edit: As a disclaimer, the author has been informed by his editor that he is required to say that the above is a terrible suggestion and that one must not attempt to bounce spheal, lest they wish to be “Ice Balled in the face” for their efforts.
Sealeo
The Ball Roll Pokémon
Type: Ice/Water
Official Registration #: 364
Entry: The evolved form of spheal, by battle experience. Contrary to popular belief, sealeo are large, seal-like pokémon famous for balancing objects—including spheal—on their highly sensitive noses in order to thoroughly investigate their properties. Celio, whose name is a homophone to the pokémon species, is the administrator of the Sevii Islands storage system and regrets to inform all readers that he cannot, in fact, balance anything on his nose at all, short of his glasses.
Walrein
The Ice Break Pokémon
Type: Ice/Water
Official Registration #: 365
Entry: The evolved form of sealeo, by battle experience. This large, walrus-like pokémon is rarely found on the beaches of colder regions. It is known for both its massive tusks, which are capable of shattering thick sheets of ice, and its blubber, which is capable of protecting itself from both subzero temperatures and physical blows … which is odd to say, as walrein’s primary weaknesses are actually fighting-types, rock-type techniques, beartic claws, and human-made harpoons, all of which the author is told are rather physical in nature.
