game stuck

HELP! I get to the level with two scenes: 1) a living room full of objects, with a staircase at the right, and 2) a desert scene with an old wooden sign pointing to Casablanca on the left, a water buffalo to the right. I found all the items, figured out how to get the flower blooming. But now there's nowhere to go. No "Continue on your journey" sign. I can't figure out how to move on the the next step. any ideas?
