evidence 1: if golfball wasn't born with dimples, then how come whenever she gets recovered, her dimples are still there?

evidence 2: if bozo's body isn't there, that can mean that due to the walls and floors overgrowing, bozo's body could've turned into a fossil, meaning that their body was never recovered, but we know golfball has been recovered, so it can't be golfball.

evidence 3: this might be a little controversial, but given how smart golfball really is, i dont think she would hide behind a plant pot as i think she would be smart enough as to not do that.

conclusion: okay, so golfball isn't bozo. but then, who is bozo? well, i think bozo is some sort of sibling of of golfball, as we know they must be related in some way, as i dont think jacknjellify put that flashback there for nothing. this may explain why golfball gets mad at being called bozo (besides the fact that bozo is a teasing name) because it remind her of when bozo died.
