This is how Prince Tahu is born goes in Magical Mystery Cure.
Applejack: Tahu? Is that you?
Bulkhead: It had better be.
Rest of main cast: [gasps]
Twilight Sparkle: Whoa.
Applejack: Wha... I-I've never seen anything like it.
Bulkhead: Me neither.
Rainbow Dash: Ha! Tahu's got wings! Awesome! A new flying buddy! [laughs]
Rarity: Why, you've become a /Alicorn hybrid. I didn't even know that was possible.
Bumblebee: [beeps] (translation: Me neither.)
Pinkie Pie: /Alicorn hybrid party! [blows party kazoo]
Fluttershy: Wow... You look just like a prince.
[Princess Celestia flies in]
Princess Celestia: That's because he is a prince.
Main cast: Huh?
Pinkie Pie: Hold on a second!
Smokescreen: Wait. What?!
Twilight Sparkle: I'm so proud of you.
Tahu: A... A prince?
Princess Celestia: Since you've come to Equestria, you've displayed the charity, compassion, devotion, integrity, optimism, and of course, the leadership of a true prince.
