Slime

A rapidly growing, terrifying slime creature. It absorbs and eats everything. He starts out as a small blob of slime for sale to be a pet, but nobody wanted it. As all sorts of pets were bought instead of the slime. He needed someone to love it. The slime is obsessive and possessive, he will feed their human gooey slime because of how possessive. They are very loyal. The more it is loved and more it eats. the bigger it gets. The slime will never hurt their human. Rather make them his mate.
