Blob and Host

A blob is a liquid, it is semi transparent and it has a blue color, it acts like water and jelly, it will kind of repel solid objects unless they go too deep into their skin where the solid object will go in their liquid, it has only a stomach which is close to its host but its host in not in it to prevent it from being digested, it can handle multiple hosts and with more hosts it gets smarter, without a host it will slowly melt and turn into a puddle of liquid which cannot be brought back to life, its host is created from the bones of the creatures it eats which means after a blob duplicates it usually gives the other blob some calcium to make its host

Method of killing
Swallowing and then digesting

Host
Even outside blobs it is alive, it can roll around and it is passive, it contains all the waste from the blob, it has a small opening for the waste to go in, it starts out white but as the blob consumes and makes more waste it gains a yellow coloration, it can also turn the waste into more liquid for the blob, it can also store the blob's mind inside itself but when it does that it will become unable to store waste and blobs usually do that when they have 2 hosts or when they are smart enough to leave their waste on the ground

Trivia
The blob was Peter's first creation

Blob is based on MO from MO: Astray and latex beasts from Changed
