Mega Bat

A Mega Bat is a creature that spawns on any island during a Spooky Festival. It is similar to the Grinch sea creature and the Mayor Jerry mobs, where it only takes 1 damage no matter what each hit and drops items on hit instead of on death, only it drops candy instead of gifts and has 100 health instead of 10.

 SPAWNING 

The Mega Bat can spawn almost anywhere in the map. It can spawn even in the crypt caverns. This can lead to some interesting spawn places like in the mountain or next to the void.
