Avalanche

Avalanche is a monster added in the Neapolitan update found in the Glacier.

Avalanche
The Avalanche is an immobile enemy who periodically spawns an enemy. What enemy they spawn is completely dependant on the room and can range from any kind (i.e Gapers, Snowflakes, Sasquatches, etc). The enemy always appears as a smaller version of its regular counterpart and has roughly 2/3 of the original's health.

The Avalanche has a spawn cap of 3 enemies at a time and will only continue spawning once one of the enemies is slain. Upon death, the Avalanche spawns a regular version of whatever enemy it was spawning.
