Magical Eggs

Players stumble upon the strange, violet egg. It is approximately two feet tall and although its shell seems to be translucent, it is actually impossible to take a peak into its inside. If the players choose to crack the egg, roll 1d12 to determine what's inside:

1. Cockatrice chick, helpless but friendly (can be trained as pet);
2. 2d8x317 gp, covered with manure;
3. Cloud of colorful fumes. You may roll this table to determine its nature;
4. Void Dragon hatchling;
5. Human child / small humanoid skeleton (inanimated), holding a gem in its hands;
6. Egg explodes with cloud of filthy rags - 1d3 concussion damage in ten feet radius;
7. Large, animated skeleton of a duckling (pathetic stats);
8. Ordinary contents of an egg (edible, 15% for being rotten);
9. Young Crystal Serpent;
10. Egg is empty but it emits strange, ringing noise when cracked open;
11. Trans-dimensional portal opens;
12. FML, there's another egg inside this one (but it is bright green)!
