Voyage to the Bunny Planet by Rosemary Wells contains 3 short stories in which three bunny children experience a particularly bad day.
When Claire gets overwhelmed by the mishaps, she visits the bunny planet, where she gets to pick the First Tomato of the season.
Poor Felix gets sick during art class, but he's able to retreat to the Island Light, where he spends the day in the lighthouse.
Dealing with his relatives is exhausting for Robert, so he takes a break to lay his head among Moss Pillows.
Each bunny child returns to reality with a better outlook on the day. These short stories help children learn that sometimes one has to disconnect from the outside world and find peace inwardly in order to deal with life. This was a favorite from my childhood and I hope many other children will enjoy it for years to come.
