Polysaurus Rex



The Polysaurus Rex was a thought to be extinct two-headed dragon that guarded two doors in the Forbidden Zone. Described as a "bio-mechanical watchdog", one of its heads would always tell the truth, whilst the other would only tell lies, though it was impossible to discern which one beforehand. Sally Acorn encountered it whilst on her soul-quest from Julayla and was able out outsmart it. (IYF)
