After a rocky start and a lot of dangerous adventures, the day everyone has been waiting for has finally arrived: Jonathan Healy and Frances Brown are going to be married, and none too soon, since their first child is set to arrive at any moment. Alexander and Enid couldn't be happier about their son gaining a wife and a child, while giving them a daughter-in-law. The mice have been celebrating for weeks. If only Jonathan and Fran were so sure... Marriage is a big step, and Fran is terrified of what her future will bring. Is this her happily ever after, or just one more short-term home in a long string of the same? Help comes in the form of her old circus friends...but that just raises more questions. Will she ever be happy holding still? And what does it mean to be married in green? You are cordially invited to join the Healys and the members of the Campbell Family Carnival on the joyous event of the marriage of Jonathan Healy and Frances Brown. Assuming they go through with it. Everything changes today.
