What do you think Rainbow Dash's pet will be? Or do you think she's better without one?
I actually have a small problem with the main characters having pets, and it's not just because they are ponies. It's because, with the exception of Spike (who I don't count as a pet as such, because A) he's intelligent and B) isn't really treated like a pet anyway) and Fluttershy's group of forest animals (since that's her skill anyway), the pets are just there. Until Gummy, Opal and Winona have a bigger role to play, I might not really consider them properly, as they're just there so the main characters have pets.
That said, if Rainbow DOES get a pet, I'm expecting some kind of bird or other flying animal (though mainly a bird). Why? They go fast and they fly, perfect for her. Though if they're going for comedy, the idea mentioned earlier about a tortoise would be great. =D
I'll wait for confirmation on the claiming thing though, maybe a list so I know which ones I can pick. (Maybe Twilight or Applejack? =/)
