Peter's Specimens in TBoI

So Peter decided to add his specimens into TBoI as custom characters

Smily
Smily has very high stats and flight, however items are replaced by pickups which makes you unable to get any items as Smily

Tainted:
Smily still has flight but now it has very low stats but item rooms and boss rooms will have 3 items instead of one, you can pick one of them for free, the other ones will have a cost like 1 key, 1 bomb, 15 coins etc

Hungry Demon
Hungry Demon starts with 6 health and flight but very low stats, he has a melee claw attack and he starts with an item which appears in his card slot similarly to Tainted characters, this active item is called "Demoniac Teleport" which has a 5 second charge, when you use it its charge will not go away, time will stop and everything will become darker, on this mode you cannot attack and you have to use the item again to go back to the real world

Tainted:
Hungry demon still has flight but now he has 3 health and the same stats as Cain, he still has the Demoniac Teleport item and he starts with a The Lovers card, he also lost one of his arms and he can only attack with one arm similarly to how Cain can only shoot with one eye

Woormy Charles
Woormy Charles is pretty quick and he has a melee whip attack which has a very high range but very low fire rate, this attack can go through rocks, he has the same stats as Isaac, this whip attack is actually an item called "Charles' Arms" which give you a whip attack which cannot be removed from Woormy Charles but can be removed from other characters

Tainted:
Woormy Charles is now a ball of tangled tentacles, now he has higher fire rate but lower damage, he now has a larger amount of tentacles which he uses to crawl around with, he has a higher fire rate and every time he attacks he will also attack with 2 other tentacles towards random directions or an enemy if there are any behind Woormy Charles, this whip attack is actually an item too called "Tangled Tentacles" which give you the same whip attack from Charles' Arms but you will also attack with 2 other tentacles which will attack a random direction or a nearby enemy
