Snover
The Frost Tree Pokémon
Type: Grass/Ice
Official Registration #: 459
Entry: Although this short pokémon strongly resembles a snow-covered tree throughout the year, it is actually highly responsive to the seasons. For one, it migrates: in the warmer months, it migrates to the top of its mountainous habitat to live in the colder climes, whereas during the colder months, it migrates to the food-rich foothills to breed. Likewise, during the spring, just before it makes its journey up the mountain, it sprouts berries the texture of frozen treats all over its belly and chest. … The author highly suggests that you do not put too much thought into the second trait.

Abomasnow
The Frost Tree Pokémon
Type: Grass/Ice
Official Registration #: 460
Entry: The evolved form of snover, by battle experience. These giant snow monsters are known for their reclusiveness and protectiveness towards their own kind. To protect themselves and their newborn snover, they whip up giant blizzards to conceal their location. In that way, their snover may get up and migrate up their mountainous territory in peace. Travelers who wander through these abomasnow-induced blizzards may stumble across what appear to be moving parts of forests. On the negative side, this greatly increases those travelers’ chances of getting horribly lost within the dizzying, bitter-cold storm. On the positive side, such a sight is incredible to behold if the traveler is on the right combination of psychoactive substa

Actually, never mind.

Mega Abomasnow
The Frost Tree Pokémon
Type: Grass/Ice
Official Registration #: 460+
Entry: The advanced form of abomasnow, via abomasite. Upon mega evolution, abomasnow not only gains a considerable boost in its ability to command ice and a special ability that calls down hail storms but also a fearsome, quadrupedal appearance and the predilection of defending its mountain territories by charging downhill towards intruders. In other words, abomasnow mega evolves into the living nightmare of anyone unfortunate enough to have played SkiFree.
