There have been a number of those working their way into the hobby over the last year or two. They have the tips of a Hammer/paraancora, but here and there youll see a tentacle 'bubble' into smaller divisions like a Frogspawn/paradivisa does. I have yet to see a definitive ID on these, and around here weve just been referring to them as either Frogspawns or Hybrids (whether they are or not.. who knows).
