In preparation of ultrakill update I made this silly goober. The boss fight is a prototype and preferably would be harder. Change anything as much as you want. (I was going to add a big shockwave attack but I got lazy.) Also add the music for minos prime because it is peak. The clue for this slugcat in the menu is: "The mind of a soulless corpse" and maybe people associate it to the rot and click on it to get a code to enter the boss fight area on the computer.
