In Upside Down Town instead of the sun coming up each day and seeing the moon at night time. We see a moon in the day and the sun at night.
In upside down town instead of rabbits nesting and living in burrows they live in the sky. Not too many pop up at a time so take a seat on a cloud and have a picnic. Some rabbits are so nice that they will come up to you and give you a hug.
