My drawing

Ok so my frist listing is Ocean OF Fear I was and still am a little cofused on what that ghostly figure coming out of Finn s bellybutton was . Anyway I also have one more thing to point out has anybody ever noticed a little snail in the corner of almost every episode? plus I have always wanted to know what happened during The Great Mushroom war like what happened such as how did Simon meet Marceline as a child. What I d like to point out my confusing how did the war eve start ? Anyway that's all my qestions don't worry if you cant answer some of these qestions or worry about what to say because I don't care what you say ...no realy I highly support peoples thougts . Well thanks for reading bye;D
