There is to my knowledge only the one Plush UK exclusive pony available - however in the UK there are also four pyjama cases, twice as big and twice as floppy as a plush and every bit as cute.
 
 

Although looking much like Surprise, Plush Honeycomb is a pony in her own right. She has blue eyeshadow which is unusual for Plush ponies and her symbols can be clearly seen as four bees.

Although we did have a large number of Plush ponies in the UK, most of which were sold in the USA also, we also had these rather special and endearing pyjama cases. Aproximately twice as big and twice as floppy as the Hasbro Softie plushes these were made in the UK by a company called Telitoy. When they were new, these large and adorable ponies had a rosette attached to their cheek with their name on and to my knowledge there are four of these in existance.
Cotton Candy and Bow Tie, the original two are in a lying down pose, with their symbol sewed on pieces of cloth and their eyes closed. The zip is along their stomachs and their feet can be velcroed together to hide this.
Trickles, and Starshine sit up, with open eyes and plastic stitched on symbols. Starshine in addition has huge floppy wings. (sorry, no pic of Starshine available)
