Tired from spring cleaning, Mole ventures out of his hole for the first time and stumbles across a river and a new-found friend Ratty. The two friends enjoy themselves then call on Mr. Toad, who takes them for a trip on the open road by gypsy caravan until a passing motor car causes the caravan to crash and Toad to develop a mania for driving motor cars. Back at the riverbank Ratty gets a temporary phase of a desire to emigrate but Mole snaps him out of it.
