Count along with Mother Duck as her ducklings try to waddle across the bridge. When a sudden gust of wind sweeps one of Mother Duck's ducklings into the river, she doesn't know what to do. With four ducklings on the bridge and one below, Mother Duck is torn as to which way to go. Suddenly, a second duck falls and Mother Duck grows more panicked. Should she stay on the bridge or fly down to her ducklings in the river?
As she paces and frantically quacks, the remaining ducklings playfully plop one by one into the river until all of the siblings are happily floating along. Now that all five ducklings are safely in the water, Mother Duck flies down to join in the fun, relieved to have all her ducklings together again.
