Like Smurfette, Baby comes with his own hut but is not stationary. He crawls around in the village and from time to time falls asleep (sometimes at really unlikely places, for instances the at the middle of a bridge). He is available for 30 Smurfberries and because he is still small and does not need as much space as a grown Smurf his mushroom house is smaller then the other ones, occupying only 2/3 of the space than a big mushroom house would need.
Baby Smurf does not have his own mini-game, but he gives 60 XP indicated by a milk bottle over his head. This happens six times a day (every four hours.)
