The last trophy isn't difficult to get, but it slightly more hidden than the rest, so here's your help.
In the last level look for an outline of a door. It will be underground. You actually walk through the "dirt" to get to it.
You'll have to perform some feats in there to get it, but that's the kit trophy.
