Huh. That's definitely the game, though the version I played had half as many colors, if even that many; only one pterodactyl and could handle up to four players; though thinking on it, the colors might've been reduced to help the processor handle the "up to four players" part. Maybe I preferred to think of that damn pterodactyl as a dragon because dying to even a cheating dragon at least has some dignity. It's a fucking dragon.
