The Smurfs' Nightmare (also known as The Smurfs 3) is a game released for the Gameboy and Gameboy Color.
This time evil Gargamel casts an evil spell on the Smurf Village. All the sleeping Smurfs are trapped inside horrible nightmares. And you, brave Smurf, should go into their houses and rescue them. To enter the house you should have a key for it. Each house represents a different environment as well as different monsters and goals.
The gameplay is shown in 3rd-person side-scrolling view, where you should move, jump on the opponents to eliminate them, use different mechanisms to reach certain places, and collect the necessary number of magical leaves to finish the level. Different goals should be performed also such as to find the carrot in the Kitchen, etc.
The Gameboy Color version is not usable on earlier versions of the Gameboy.
