I think Blackjack Squarepants is Blue's son. Reason #1, he is Spongebob's oldest cousin while Blue is Spongebob's oldest uncle. Reason #2, he looks more like Blue than Spongebob's other cousins. Reason #3, he lives next to Blackjack. Seriously, who lives next to their nephew? So therefore, I think Blackjack is Blue's son. What do you guys think?
Uh, you do know that Blackjack Squarepants is already listed as Blue Squarepants' nephew right? Gotta look at their pages and look in their information page. Just want to point that out. Lightning Flash (talk) 15:19, October 29, 2012 (UTC)L.F.
