Simon and Milo are twins. Milo is very outgoing, and Simon tends to be shy. They found common ground and comradery when they took Petie Bird's advice and invited their friends to their cupcake ball. Simon and Milo experienced the fun of party planning, getting together with friends for music, dancing, and cupcakes, and lots of crazy kitty antics. Simon found out he had quite a few friends after all. At the end of the day, Simon said it best, "Just like grapes, good friends come in bunches. We certainly have a bunch!"
