Three different behaviors that you made:
1. The butterflies move in a circular pattern
2. The roofs of the houses jump (they remain attached until the apex of the turtle shell movement)
3. The turtle walks

One behavior that is not simple:
Not simple: The trees are squashed when it encounters the turtle

Other Behaviors that you made: (backup in case something above doesn't count)

- The ruins have a chance to disappear and a chance to reappear on a timer
