"Pinkie Pie's Singing Telegram (Unused Version) - My Little Pony: Friendship Is Magic" is a high quality rip of the unused version of "Pinkie Pie's Singing Telegram" from My Little Pony: Friendship Is Magic.
Joke[]
The advertised track is mashed up with "Kyle's Mom's a Bitch" from South Park, specifically the version from the episode "Mr. Hankey, the Christmas Poo". At 0:40, the shotgun sounds from "pinkie just had sex!!!!!!!!!!" by theburninice1 play in-between Cartman's dialogue from right after "Kyle's Mom's a Bitch".
