Snowman
Sims are able to make snowmen in The Sims 2: Seasons Expansion Pack, if snow has fallen.
Your sim can make a normal snowman and sometimes a devil one.Once made, Sims only have the action to knock them over, but a Penguin will come to your lot and speak to them knocked over or not.
Snowmen will melt if all the snow on a lot has melted. If a neighborhood has winter all year long, the snowman will never melt.
