My Little Pony: Friendship is Magic - Six alicorns

Yep don't forget the only Filly Alicorn around, "Princess Erroria":

but… I guess the reason why he/she didn't mention her, is because she was only an Alicorn in Twilight's imagination, so it wasn't real, I guess… but it's nice to see an actual child princess in the show, she was even an Alicorn Filly before the made the Princess Skyla toy (who I thought was going to be Cadence & Shining Armor's child, but apparently not),

& also, am I the only one that realized that the non-royal Alicorns one of each gender & age of a pony, like how Erroria's an Alicorn Filly, Twilight's an Alicorn Mare, & Neon's an Alicorn Stallion?, I'm not sure that mean's we're going to see an Alicorn Colt later in the series, but we'll see for sure…
