You need a friend and the two must just do stuff with the Joy-cons, there is only one minishame for a single player, it is just embarrassing.
The left guy must act like his Joy-con is a knife, and is wanted to chase the right one, and must stab him in the heart, after 10 seconds the left fails.
The right one must shove there Joy-con into the lefts Joy-con, which is held in their penis area.
Do nothing and then a random side wins.
After this point all minishames get unlocked after playing these games.
The left shoots right with a crossbow and kills the right one automatically.
One player only, the left must guess what diaper has the most poop, and must eat it.
The left Joy-con must slide over the right one.
Use your Joy-cons to slap a meteorite at each other until one misses, and the other one dies.
Many random people fight eachother on teams, simple isn't it?
It choses what game you play.
