Build pre-defined animals by dragging the shapes from the left side into their correct **dotted outlines**. Once all pieces snap into place, the animal will come to life and run/swim/fly across the screen and back! When the animation finishes, the next puzzle loads automatically.
Use the bank of shapes on the left to build **your own animal**. There are no rules or targets. When you are done, click the **'Run Animation'** button to watch your creation perform a mirrored, round-trip animation! Use the **'Clear Shapes'** button to start a new design.
