Question: I live in water, but not in the same place. Sometimes it’s drinkable and other times it's not. I am either a hunter or gatherer. I am known for being gentle and easy, but I don’t live long. You will know me by my large eyes and goofy lips. People know me by my slimy body. I can be found in your house or out in the wild but never in between. I am friendly so I will likely be your friend in school. What am I?
