"So you've come to try the egg factory," says a chipper ylla in a hard hat. "The factory is where we store and nurture ylla eggs before they hatch into young ylla. Since you're new here, and not a ylla, we'll assign you the job of moving the eggs out of the storeroom."

"The egg factory rules are simple. There are five rooms with multicolored eggs. You'll need to collect eggs by getting two or more of the same color. You get points for each group of eggs you successfully remove. The more eggs you remove at once, the greater the number of points you will get. If you find that the eggs are too far apart, you can collapse them to bring them closer together. Generally speaking, dropping eggs is not a good idea, so we frown on collapsing. You'll be allowed to do it, but only when you've earned enough points."

"We're not sure how skilled you are with ylla eggs, so we'll be starting you with one of the easier rooms. If you do well, we'll assign you to more difficult rooms. If you manage to do well in all five rooms, you'll be rewarded for your labor."
