Kaa takes Simba, Buckshot, Toy, Thin, and XL down to the river for a swimming lesson. But the current turns out to be so strong that it sweeps them away, and they end up falling over a waterfall and crashing into a dam built by a family of beavers. All the beavers' hard work seems to have been destroyed, but Kaa and his young friends set to work to repair the damage.
