Fakemon: Mr. Slime

Mr. Slime are a dark/psychic fakemon species based off of the scary/horror clown trope, there's lots of mythology and misconceptions about them luring in and eating children, but in actuality Mr. Slime tend to get along better with human children than adults and will often willingly allow children to capture them without putting up a fight, that doesn't mean they won't occasionally attack adults though

Unlike most Pokemon, their shiny varient is actually less popular than the normal coloration Mr. Slime because their red drool grosses and/or creeps a lot of people out
