I destroyed the universe. All the backup Jools are gone! Luckily we have multiple backup Jools in storage just for this purpose. Every few months the Kraken eats Jool and takes its place, but no one notices because it's the same color and shape. Then we tell him to move along and he eventually leaves but not without changing some of the physics first, and we put in a new Jool to replace the one that was eaten. When this happens, we increment the number in the bottom right corner of the main menu screen...
