I'm very pleased with this one. First I made a background underwater scene. Then I made three interactive tracks.
The first track is for the plane. The plane moves from right to left getting higher in the sky at it goes. When it hits the cloud it has a little trouble and someone (either Michael or Ava) needs to help the pilot get through the cloud (by threading the bead through the loop).
The second track is for the boat. The boat begins by moving from left to right along the top of the water. Each time it hits a wave it needs help. After it hits the third wave it sinks down to the ocean floor.
The third track is for a fish. He starts at the bottom in his home by the coral before going on a treasure hunt. He works his way up to the top of the underwater mountain where he finds a treasure chest.
Here are the beads in their beginning positions:
And here they are in their final positions:
