The first playsets, and arguably the best of G1, came out in year 2 and were crowned by the magestic Dream Castle which introduced Spike the Dragon as a companion to the unicorn Majesty. Year 2 is also where we see the very first baby pony, Ember, who was available as a Horseshoe points mail order offering only (horseshoe points came on the backs of pony boxes). This first Ember was the pink version.
