These are the ponies that were included with games in 2006.
Puzzlemint
Puzzlemint is a white pony with yellow, purple and pink hair. Her cutiemark is a puzzle piece with a magnifying glass. I associate her with Professor Layton (Since she loves puzzles and in the cartoon is British) and since thats one of my favorite games of all time she's very special to me. I recieved mine in great condition.
