To save Monster Land from the evil Meka Dragon, you've entered his castle and are about to go into battle. If you defeat the dragon, a terrible surprise awaits you... a curse! You'll turn into a lizard-man, and more. The only way you can return to human form is to find the Salamander Cross, a magical item with the power to remove curses. But where is it hidden? Finding it is an adventure that will take you across strange lands, against strange creatures, into battles where you never know what strange shape you'll turn into! Hawk-man, Lion-man, and more! You'll be able to buy armor, weapons and use magic items! Hidden rooms hold even greater surprises! Can you beat the dragon's bosses and recover the Salamander Cross? When you look at the shape you're in, it's your only hope!
