Correct me if I´m wrong, but I think “The Hoobs Playtime Gift Pack” is a New Zealand/Australian exclusive limited edition. The game disc comes in a music-CD style case, a concept I have only seen for other New Zealand/Australian releases, like “Blue´s Clues: Blue´s Big Musical”. On the otherhand there are multi-language on the back of the cardboard box, so I´m not entirely sure. The disc case back has “Not to be sold separately” written on it.
The box contains, except for the game itself, a character from the TV-show as a plush toy. I have never seen this limited edition packed with any other figure than this green one.
You can find this collectors item on ebay from time to time, and is often not too expensive to get your hands on.
