Ur A Chemical

ok so basically <USER> is some sort of slimy-like chemical from the planet Uriel and scientists say it is one single substance, a damn pure substance that is ALIVE <USER>: a tiny little puddle of paleish pink jelly-like thing with some white outlined empty circles for eyes and a big ass mouth that can stretch up really high to consume things, sometimes it gets a little string from top to bottom from opening it too fast, making itself stretch, 61 years old, <USER>can slither around and speak in a voice that sounds like how a frog would speak, but as if it is playing underwater, and finally, <USER> can change sizes from a few hundred mililiters to 10 liters, maybe 12 or even 20 but rarely. <USER>just compresses, i guess. so in this story <USER> has been found living in the forest and has been captured in sleep to a lab.
