SpongeBob's Family

I decided to attempt to figure out Spongey's family tree. I was trying to figure out which relatives were on which parents' side.

Finally, I decided on this: SpongeBuck, due to his last name SquarePants, is on SpongeBob's dad's side. He looks exactly like SpongeBob, so it can be assumed that SpongeBob gets his looks and square shape from that side.

SpongeBob's mom doesn't look much like him, except she has his eyes and a similar nose. Family members who looks more like her, but with those features, are probably on her side.

Oh, and on the episode Blackjack, they said SpongeBob's dad was named Harold. Also, Blackjack calls SpongeBob's grandmother "grandma," so I guess she's on his side of the family. And I am just assuming that Blackjack isn't Blue's son, and is the son of somone else on SpongeBob's mom's side.

NONE OF THIS IS CANON. I'M JUST MAKING LOGICAL GUESSES. Well, except maybe SpongeBob's parents getting married and having a kid.
