When was the last time you looked under the bed? You'd be surprised what oddities you find there. Monsters, Wraiths or a stinging moustache? The only winner in this game is the first one to fall asleep with no fear, but be careful because you can easily get in each other's way.
In Mumusok, a player can draw as many cards as he wants in his turn to get sleep points and advance on the scoreboard. But if he encounters 3 Mumus from the deck he will be caught and lose the points he scored in that round. However, the deck also contains action cards and event cards that you can use to either advance yourself or to advance your opponent.
The scoreboard consists of 20 pillows, but the colours of the pillows have different properties that either make it harder or easier for the player to advance in that round.
