Notes[]
Fun facts: this item is from the very first collectors edition of the game in 2004.
If you can find and buy a copy unsealed, the baby dragon is likely to be claimed (gone), but if you find one still factory sealed, it should have the card with a code to enter to get this house pet.
The original collectors edition came in a tin themed for the game, in the era when software was still primarily sold and loaded using CDs. It also contained game booklets, a poster and more.
