Here's the evolution of the ice Bulbasaur I posted earlier
I took inspiration from Glacier buttercups and snowflakes for the bulb and leaves!

Though it lives in the icy tundra, this IVYSAUR has a surprisingly warm body temperature due to the energy beginning to pour from its growing bud. It hunts during the warmest parts of the day using its powerful ICE-type attacks, and retreats to its burrow when the temperature drops too low.

Havent done Venusaur yet but I plan to!
