Opaque "Frost Cube (working title)" mob for snowy biomes; melts from heat.

I would like to propose adding the "Frost Cube (working title)," a new environmental and creature mob designed to enrich snowy (cold) biomes. Appearance & Features • Size: It has the same cubic size as a Magma Cube but features a translucent, ice-like appearance. • Key Feature: Its most defining characteristic is a snowflake-shaped tail attached to its back. Behaviors & Mechanics • Spawning: It only spawns naturally in cold biomes, such as Ice Plains and Ice Spikes. • Melting Mechanic: Just like ice blocks, if it enters a hot biome like a Desert or Savanna, a unique melting animation triggers, and it will eventually disappear entirely. Conclusion If added, this mob will bring wonderful dynamism and a realistic ecosystem to Minecraft's cold areas. It will also create a perfect game balance as the ideal counterpart to the fire-resistant Magma Cube found in the Nether. Thank you for your consideration.
