THE EGGS HATCHED!!!!
Mark, the Grade 6 teacher, left for Christmas to visit his parents in Kitchener. Jari was left in charge of checking the eggs to see if the temperature and water flow were good. On January 2, 2002 Jari was surprised to find that two of the eggs had hatched! He said, "I was very surprised, happy and excited. I saw Marie first, and asked her what to do, but she didn't know what to do. I asked my dad what to do, but he told me to wait for Mark to come back."
