A licensed TV-tie-in adventure that came out only in North America and is pricier than most of its neighbors.

How it was made

Before you buy

Only a North American release exists, so there is no regional choice to make. Loose, this is one of the pricier carts among the North American releases and well above the median for its year. For a copy at this price, ask for a photo of the board and compare it with the board listed on this page. Check that the manual is there, since it is the part most often missing from a complete copy.
