Rhinocephants on the Roof

Ages 3-6.
Daniel is visiting Grandpa and Grandma. At bedtime Grandpa reads him a story about a brave soldier. Grandma sings a song about a brave mouse running up a clock. Now Daniel has to sleep. But the bed does not feel as comfortable as his own bed. The room looks darker than his own room. And he hears a strange noise on the roof. It sounds like huge, heavy animals dancing and prancing around the chimney. "Grandpa!" Daniel cries. "Grandpa, I hear something on the roof!" "What do you hear, Daniel?" Grandpa asks. "I think it might be rhinocephants, Grandpa. A whole herd of rhinocephants."
