Mog Mog MZ800

Hi back in the early eighties our family had a MZ800 with a tape drive. A tape that come with the machine had the game mog mog. I have never been able to find a working copy of it online. The game had a character sort of like pac man that would dig under ground and would get chased by blue legs and red legs and a ghost. Your goal was to eat the presents and return home. There was also yellow squares called warp stones thatwould transport you to random locations. I used to "hack" the basic program and add extra things to it for fun. I would love a copy if any one could send me a link or a file of it, it would be great to show my kids all these years later. I have found other MZ800 games but never this one. We also had a game called Egg and a MZ800 game called battle Vulcan as well as clones of Frogger and c64 games.
