The only ones in that list that actually have tentacles are the BO Mutants and the Octopus-themed ones (counting Meat Eater, it looks like an Octopod with a plant on it). Krawlie and Hexapod have lengthy tongues, stingers, and multiple legs, but no tentacles. Blob, Edger, and all the Acid variations are goo monsters, which have their own little sub-fetish away from tentacles (goo girls are more popular, however). Gnawer, Gnasher, and Ruminator are all snakes, that's Ophidicism.
This is reminding me of that flash game and all those animated gifs that use edited sprites from the game. Marle/anything from the bestiary is a sure hit.
