It was released on all three of Nintendo's systems at the time:
The Game Boy version was ported for the system by Enigma Variations Ltd.
The game is a side scrolling platformer adventure game that is very similar to the original Addams Family SNES title. A major source of criticism for the SNES version was the lack of a password feature. A password feature is present on both the NES and Game Boy versions.
The plot of Pugsley's Scavenger Hunt centered around Pugsley's attempts to win a scavenger hunt challenge proposed by his sister, Wednesday. His hunt takes him to the bedrooms of each member of the Addams family in order to find one item from each.
It's interesting to note that the NES version was not a direct port of the SNES version. The NES version was actually based on the previous Addams Family game released for Super NES, Mega Drive and Amiga, showing the same levels, enemies, items and gameplay but with Pugsley as main character instead of Gomez.
