Trying to remember the name of an arcade puzzle game

Board 8

I've been trying to remember the name of an arcade game, but I'm not having much success. It would help if I knew the name of the game it was based on - take over tiles by either creating another piece next to you or moving one of your pieces next to your opponent's, thereby capturing the space. I remember the game had multiple bad guys to compete against, which essentially stood for the CPU difficulty level. I could have sworn one of them was named Muck Man and another was called Colony, but Google doesn't turn up any results. Do any of you know what game this was?
