In the first book of the series, Lily and Trooper wake to the sounds of birds singing. It must be spring. What better way to celebrate than a picnic breakfast? Suddenly a cow surprises them, sending them scurrying up a tree. Later, they swing a little too high, fall off, and land in a group of very surprised sheep! The sheep lead to pigs, which lead to mud, which leads to a mother duck and her ducklings. Finally it's time for a warm bath and bed.
