These are ponies in Gi-Go’s Tootsie pose. Two are marked Manley 2003 on the belly and. The others (sold at Walmart in family packs) are unmarked, but I suspect they are by a different manufacturer as the quality feels different. These all have the same symbol of three stars.

No markings:

This one’s mane is a very fine and soft texture, like MLP Watercolor Baby Sea Ponies. The tail is a more traditional hair type.

Manley markings:

Short Head:

This purple one was sold in a Wal-mart pack that included the Manley model above, but this one is marked simply MADE IN CHINA. See in-package pictures here.
