*NON-SPAM COMMENT*
Even though hippogriffs may be sized differently than average ponies, they are the same size in Pony Town.
Although this add-on doesn't turn players into a pony themselves like on PC, it's still enjoyable. With more characters in the next update, MLP will be more enjoyable in Minecraft as it is while watching the show and creating fanart.
