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

I haven't watched any of the videos so I don't know how the traps are shown in this GP but I remember the traps being pretty visible in WA, as well. At least I never had problems seeing them. I seem to recall it was more a matter of whether your Sim would trigger a trap or not and, in some cases, what would happen when something was triggered that made it more exciting.
