Now personally, I usually watch My Little Pony in English. However, I have found that the show is actually very interesting in Spanish.
The other day I was watching A Canterlot Wedding in Spanish and listening to the This Day Aria. In English, Chrysalis sings
"Everypony will gather round
Say I look lovely in my gown
What they don't know is that I have fooled them all".
However, in Spanish, she says something a bit different. A little higher on the "oh my" meter. She sings:
"All the ponies will gather round
Say I look lovely at the altar
But what they don't know is that I hate them in reality"
Well. Okay angry.
That is all.
