1990:

THE ROCK-A-BYE BED

Another of the smaller mini-playsets from the line, the Rock-a-Bye bed was literally the most uncomfortable sleeping place for any self-respecting pony anywhere in Ponyland. It comprised of a plastic aqua base (yes, a plastic matress) which came with a headboard with a wheel spinner that could change the image to night or day, depending on the mood of the owner. The bed got its name because it did not stand flat on a surface, but instead had two curved edges, allowing it to be 'rocked'. Presumably grown ponies needed to be rocked to sleep!

The set came with no pony, but a bunch of accessories, including a comb and curlers. There were also four fluffly slippers, a nightcap, an alarm clock and diary, and an eyemask (not shown, I can't find it ><).

The playset was sold worldwide under the same name.
