Not really a good splicing
It just looks like someone put an octopus on the head of a cock. If instead of feathers at the back it had tentacles or the feet were tentacles and the head looked like an octopus head it would be cooler. But as it is it just looks like a cut and paste job on two animals. I realise it isn't like that, but it looks like that. Either way the detail is pretty good, especially on the cock. And i don't think it can crow, depends on how much of the head is octopus and how much is cock. lol cocktopus.
