I just realized that the spell monkey fish (PF1e Advanced Class Guide 188; 1st level transmutation, +10 Climb & Swim speeds in light or no armor) is equally likely a reference to the Fiji Mermaid (itself used as the art for the Ningyo [Bestiary 4 206, Pathfinder AP #37 -- Serpent's Skull 1: Souls for Smuggler's Shiv 80]) as it is to Sea Monkeys (which also inspired the Coral Capuchin [Bestiary 6 66, Pathfinder AP #58 -- Skull and Shackles 4: Island of Empty Eyes 82]).
This just leaves a playable race and a magic item to complete the set of ridiculous piscisimian hybrids.
