The Adventure of a Lifetime

I have been wanting to do The Adventure of a Lifetime for a long time, just never had the chance to get it started. But now I have. It is about 4 cats – Max, Amy, Julia, and Carol – who get sucked into a mountainous world on the other side of the universe. There is only ONE way to get out – it is to hike/climb/battle your way through to the other end of the world. Amy is the most determined to get back to our side of the universe, having to remind Carol many times that you cannot just go in and out of this world whenever you want like, say, Narnia. There are many things to distract you – restaurants, city fairs, performances, everything like that. Will they ever get back to the correct side of the universe?
