EXCUSE ME WHILE I GO BUY YARN FOR THESE SOCKS.
The third picture is of a knitted Remora, which are commensal organisms that attach themselves to larger organisms (sharks, whales, etc) and eat their host’s scraps or poop. This knitted Remora has a Velcro mouth that one can use to stick onto the shark socks! PERFECTION.
