This can be done by having a sim enter a pool without any ladders, and building a wall directly around the pool edges so they can’t get out. This can be done in several dozen ways, but one of the easiest and fastest methods is by drowning a Sim in a pool. Thus, players will need to kill a Sim to get him to show up. Whenever a Sim dies, the Grim Reaper will appear to deal with them.
The first thing players will need to do is summon the Grim Reaper.
