The fleet insignia? Oh, it doesn't mean anything at all. Just that Octodad is a great father who enjoys wearing ties. Sure, he likes octopuses, too—what of it? They're nature's smartest invertebrates. 

This classic Jon Kay crest design is printed on soft District Threads 50/50 shirts designed to perfectly complement the human form. Because you're a human, and none of us here are questioning that. Each one comes with a bonus button.
