How do I get Munna to sleep in PokePark 2?
In PokePark 2: Wonders Beyond, to get Munna to sleep, you must fall asleep first and then Munna will copy you shortly after.
To get Munna to sit still long enough, get a Cleffa doll. Stand still next to the doll long enough and you will fall asleep first.
If you are trying to befriend Duosion, you will need to take a picture of Munna sleeping, so press the (-) key when Munna finally falls asleep.
