This is what my goo creatures would look like before they take on a form they love to choose from.
Sphere Goo creatures - are more intelligent than their other goo cousins. They can just simply touch a life-form and instantly get all their dna and their body features and transform into their new form in less then an hour. Some may look cute like the one above here but there can be others that can look scary or horrifying that most will want to stay away from them while others will want to study them and see what their capable of but most goo creatures of this type usually stay away from ones they deem dangerous as if they are studied by some other species they might not like or find pleasant. But there are some that gladly open up to ones they feel they can trust like how Sproket and Dnaix opened up to each other as Sprocket saved his life when he was slowly dying.
The majority of goo creatures sphere have a very large space inside their bodies that can store lots of things and can easily devour things larger then they are and shrink them down to store them inside for safe keeping. Some that get devoured this way complain about being devoured by something smaller then they are and sometimes wont even make a dent in the gooey body unless they find a way while others are willing as its a nice quiet space they can relax and wont harm the body of the creature.
