This is a group of ponies that all look a bit different, but share a code number prefixed with the letters MJ stamped on the belly or a hoof.
There are also some baby donkeys that share materials/symbols with these ponies.
I recently acquired an in-package specimen that confirms Cititoy as the manufacturer, branded as Patti & Her Pony:
MJ056B (large running, inset eyes)

MJ049 (mid-size 1, inset eyes. Symbol is either 1 star or 3 stars.)
Note different bridle colors:
MJ056D (mid-size 2, painted eyes)
MJ094 (painted eyes; fiber optic mane and tail)
MJ087 (painted eyes, baby)
