There was a Dragon Warrior Monsters game I remember slightly. I remembber the first town you started in was at the top left corner of a continent, and that to the far south, there was an area near a town that had damaging floor that I think was silver. I remember having a catmage in the game. I think there were green babbles at the first area too. I am pretty sure some people had a boss as a pet too. Maybe the Dragon Lord himself.

Ring any bells?
