Meet Robert P. Rabbit
Robert P. Rabbit is a special rabbit that can talk to certain special people with THE MARK, a spot in front of their right ear. Robert P. Rabbit (and don't try to call him anything but Robert P. Rabbit!) found GrandDad in a park one day, and the rest is history. GrandDad likes to think he found Robert P. Rabbit, but we really know the truth. Robert P. Rabbit came into the lives of GrandDad, Katie, Will and the rest of the family just when they really needed him most.
Robert P. Rabbit loves adventure just like Katie and Will, and together they solve mysteries.
