The original set of Dino Glows was released in 1997 which included three Dino Glows:

green Dippy Diplodocus, orange T-Bone Tyrannasaurus and purple Trike Triceratops.

The outer skins of the Dino Glows are removeable and reveal glow-in-the-dark skeletons.

(In 1999 the set was re-released and included a fourth Dino Glow, blue Stacey Stegasaurus).
