Ideal plantsim
The ideal plantsim is a debugging character most likely used for The Sims 2: Seasons. He is only gettable through the cheat Boolprop testingcheatsenabled. Note: his name is in lower case letters.
He's the "father" of all spawned plant babies. So the game uses his genes and that of the Sim who spawns the baby, like in a real birth.
