Yea, I'm completely in the dark about the third season, heck, I don't even know exactly when it starts!
Well, people on Youtube say alot... most of it probably untrue. That's why i'm asking here if anyone knows more about it. It does sound like it's something they could have done for one of the episodes.
I'm unsure if this is true, but I personally hope it's not true. Sea Ponies smell. I just don't think it'd fit, apart from maybe for a single episode. If they have put seaponies in though... I just hope they've done well with 'em.
I'd personally prefer if FiM stays sans Seaponies. I think it would detract from the show. It would be really awkward and odd to explain. More mythological beasts would be the best way to go.
The only thing I've heard about season 3 was something about Fluttershy having no wings. Or something like that
