Kelly/Shelly Amazons. This is a name the Kelly Kollectors dubbed the big size Kelly dolls, that came in separate sets with a friend or with her bigger sister Stacie (sold as Wee 3 Friends with her friends). These dolls had a blownup version of the smiley Kelly sculpt c1994. There were a few versions of the Kelly dolls, but only one of each of her friends Gia and Kayla. They were all made with the same head, the smiley Kelly sculpt.
Regarding the names. In Europe, the doll sets never had a "name", neither had Shelly's friends, so they go by the US set and doll names.

Something about the body type:

Regular 4" Kelly vs the 'Amazon'

(yes, all necks have broken pegs, happens more often than not with played-with 'Amazon' dolls)
