Sleepwalker somehow got transported into the Land of Nod through a portal, and are being hunted down by nightmares for unknown reasons. They have to get back to their bed safely, and are assisted by sand in their quest to escape.
Sleepwalkers walk blindly in one direction. They are not capable of controlling themselves, due to being asleep. Therefore they rely completely on the player. They cannot withstand water or nightmares, and will die on contact. They will, however, turn back when sand is dropped on them. Sleepwalkers are spawned in groups, and if all the sleepwalkers die, the player will lose the level.
On level two, they appear in the background.
Sleepwalkers appear on some gift wrap, in Santa suits.
Nitrome 2.0 and Classic skinsEdit
Sleepwalkers appear on a hill, walking out of a Portal. The Sleepwalkers in front are falling off the hill into the water. But in Nitrome 2.0 the sleepwalkers fall on the sand and walk but one dies.
