Since you used two unicorns, yes, it is a Melodeer. Congrats!
@Ogreve, I believe when you breed two unicorns, the result will be a single element, which is why many people used this to get the Melodeer (which is a pure music element). Correct me if I'm wrong, but if you breed unicorn + unicorn, the result can be a pyro pony, pandaffodil, unicorn, or any pure element, which makes sense since a unicorn is made up of 4 single elements. Breeding a unicorn with another unicorn won't get you any animal in the game, but let's say you were trying to breed for a Sapybara, which is nature/earth I believe, then you can breed a unicorn with another nature/earth and the result can be what you are looking for, or a cyclops or emerald if you're lucky. I think the result can also be a rock rhino or pandaffodil, but I'm not sure since I don't have a unicorn to test it out. In Dragon Story, if I bred a Diamond (which is basically like the Crystal Unicorn in Fantasy Forest) and pink element, it can also turn out to be a red/white dragon because that's what the pink element is made up of. Not sure if that's the way it works in FFS though.
On the other hand, I just got my 11th fail for the Melodeer and I'm hoping I get to finish this trio.
