Latest trend your crab picked up on? Looks as if your crab added an aileron spoiler to increase down force nearby circulation pumps or gyres.
Large spoiler/wings on back of imports has become a fad. So are lowered vehicles and improper camber or out of wheel well offset. Seen snails wearing sand/grip tape over shells mimicking skateboards.
Does your crab have direct viewing of entertainment system? Do you watch Fast N Furious?

Hmmm not sure what he’s been watching at the fish store but rest assured I’ll be limiting his screen time
