These are currently being sold at Dollar General stores for only $1 as "Pony with Accessories." Boley is the brand that manufactures them. So far, I have only seen them in three colors: pink, blue, and yellow. They all have rainbow hair and the same balloons symbol on their hips. They are spitting images of G3 MLPs, only scaled down by about 20%. There are no brand markings on the ponies themselves. They come with two accessories: a comb and a brush in matching colors.
Boley also makes fakies of the G3 styling ponies. Photo coming soon, I promise! Above is a photo of these ponies mint in package, and below is a shot of the back of their cards.
Below, is a Boley fakie next to a real G3 MLP, for size reference.
