The Secret Surprise Ponies, printed in Year 9 (1990-1991), weren't just ponies -- they were also jewelry boxes. These ponies are unusually large, and have "secret" compartments inside their bodies. Instead of symbols, they have colorful saddles on their backs, with hinges in the back, and a latch in front. Each pony has a heart- or star-shaped keyhole in her chest, and by turning a key in the lock, you can open the saddle, revealing a hollow space in the pony's back where jewlery or trinkets can be stored. All four Secret Surprise Ponies were printed in the same pose, the Secret Surprise Pose, which was never used outside of this set. Their saddles came in two styles, printed with either hearts or stars. Each pony came with a bow-shaped comb, a key, and either a ring or a bracelet.
