Death
There are three ways to die in Popmundo. Characters can not die from low health or mood (although this used to be possible in the past).
Inactivity
Characters will die after roughly 2 months of inactivity. Note that this is account inactivity. Logging in one one character on an account prevents all of them from dying for another 2 months.
Poison
Using a Bottle of Poison will cause a character to enter a "dying" state. After 7 days the character will die. A character that has been affected by poison can be saved by using a Shot of Adrenaline on them.
Punishment
When severely breaking the Popmundo rules or code of conduct (or repeatedly doing so), characters will be sent to the lake. Being sent to the lake is a death sentence.
