G4.5 Poses
From My Little Wiki
With G4.5, Hasbro kept the same characters that have been previously released, but updated the molds to be more show-accurate. This resulted in larger heads, skinnier legs, and a lack of eye-sculpting so any eye stamp may be used on any head. There were also a larger variety of poses from G4, with many more leg shapes and options. These ponies have two head versions for each species, barring Alicorns and stallions: closed and open-mouthed.
