Okay so here are my thoughts. I think Oda operates in a bubble of "expanding logic" like when he comes up with a good idea he creates something new to fit the idea into his One Piece logic. Like when all the techniques and powers all seem layed out he adds Fishman Karate, cyborgs, haki, or Rokushiki. There are new powers, creatures, and/or techniques introduced every arc I wouldn't limit it to just what we know or think we know right now. Before the Fishman Island Arc we didn't know about the steroids, Punk Hazard Arc we found out about artificial Zoan Fruits, and Pirate Alliance Arc we've met living toys.

As for Pappug I think he's just another fishman species. There were shark fishmen, blowfish fishman, and octopus fishman so why not a starfish fishmen? They don't all have to be strong and huge
