The space bar resets all of the sprites. The right arrow key starts all of the programs.
This was one of my first projects. I just wanted the orange fish to swim back and forth changing direction. Then I thought it would be more interesting if I had another sprite so I added the yellow fish. I turned it into a bit of a story by having the first fish appear to eat the second. I learned a lot from this about using repeat to make the code shorter.
