Welcome to Creature Corruption, a silly mod I made in an afternoon and a half.
Randomly corrupts enemy sprites, attacks & behaviours to look absurd and unfair.

Zombies who look like bats and shoot out magic missiles
Fireflies who shoot out bats which have machine gun lasers
Lanterns which drop two full heart pickups when they break
Anything could happen!!

There's not much else to say, the pictures explain themselves.
All I can wish you is goodluck, and to check the mod settings menu for a slider.

Have fun getting Meteor'd by Sprite Sheets of Hamis out there!

This mod doesn't override any existing files, it is safe to put at the bottom of your load order for maximum compatibility,
Although other creature mods may not be supported attack & sprite wise, they will still be corrupted to hell and back.
