Time to wake up that masculinity thing you sent to the moon a few months ago, and tell him the bad news; Hasbro has released a pony bath set. You can now wash your hair with Fluttershy's cotton candy shampoo, and lather up your Twilight Sparkle loofah with Applejack's sweet berry scent.
These are five bucks at Big Lots apparently, though no specific store was given.
Thanks to Rags for the image! Now go deck your shower/bathroom out with pony.
