To meet challenges of a new era, the animals created a school. To make it fair, and easier to oversee, all animals took the same subjects.
The duck was an ace swimmer, a good flier, but a hopeless runner. The rabbit was a fabulous runner, but fell behind in swimming. The squirrel climbed well, but struggled with the flying curriculum, which mandated starting from the bottom up, rather than from the treetop down. The eagle was a good climber, but insisted on his own way of doing it.
