Gasp!-Fluffle Puff
Fluffle Puff is a pony that happens to be fluffy, and not a fluffy pony. Although Fluffle Puff may or may not have inspired the fluffiness of fluffies, that character has nothing to do with fluffy ponies, and Fluffle Puff's creator strongly dislikes fluffies. Fluffle Puff is merely a My Little Pony fan character that happens to fluffy and have low intelligence.
