By definition, Jungle Adventure doesn't have real traps.
There are nothing more than obstacles that your sims have to overcome. They don't have the element of surprise. They're bluntly visible, and you know the exact danger If you directed a sim to go dare...
Lack of booby traps dose not disturb me personally. The sims is no action/adventure game type, so I pretty much expected that the traps would be fairly obvious.
