As with most games, there were a few features that didn't make it into the final version. The game was originally to feature additional levels, culminating with a fight against the "Grand Dragon". Despite the fact that the Grand Dragon never made it into the game, it may have influenced a much more popular digging game.
[Andy Walker]…when we were at the preview show, we all knew it was a work in progress. We described it as such to some Japanese people who were extremely interested. I think they were from Namco or Atari. We described how you would find the Dragon and blow it up. Not 'you kill it' but specifically 'you blow it up'. The Japanese gave us an old-fashioned look then made expanding gestures, then "boom". The point being that when we said "blow it up" they thought "inflate."
