Flim and Flam, collectively known as the Flim Flam Brothers, are twin salespony uni-colt brothers who first appear as antagonists in "The Super Speedy Cider Squeezy 6000" and return or are mentioned in later animated shorts, IDW comics, and chapter books. Flim is called Flim Skim in some merchandise.
In My Little Pony: Best Gift Ever, Flim and Flam appear in disguise selling cheap Hearth's Warming dolls in Rainbow Falls to fund another expansion of their resort. Applejack & Fluttershy foil their scheme by convincing their customers to put more time and effort into their Hearth's Warming gifts. Flim and Flam are later run out of Rainbow Falls by their angered customers, and they are last seen riding the Friendship Express during "The True Gift of Gifting".
