By definition, Jungle Adventure doesn't have real traps.

How cool If would have been If there was a trap door that would have open beneath the sim when triggered or gone over tripwire, and (s)he would have fallen in a 1x1 chamber below them. If you bought a ladder (should have listen to the recommendation tourists and retail clerk), than you're lucky to get out of a trap. If not, then you have no choice than for your sim to starve (and until food resource ran out) or reload to the past save and prepare your sim properly.
