first of all this mod is based on jabroni_mike's internet persona and the man himself, and unknownautistico's trash boy. it was supposed to have more people in it as items but unfortunately i'm too dumb to figure that out.

Installing:

Download and install MTG:  https://modthegungeon.eu/

Download Kyle's Sprite Replacement and Custom characters mod:

        There should already be guides there to help you install them.

After that download the JabroniMod.zip file and extract it somewhere.
Go to your ETG steam directory and drop the Jabroni folder in the CustomCharacterData folder, then Drop the sprites folder and the dfsprites folder in the resources folder. and then you're done, when you load in to the breach, Low Effort Cryptid (the cat) should be chilling there.
