Water-Rat decides that he will have a picnic so he invites his friends Grey Rabbit and Squirrel to join him. So they prepare all the goodies and set off in their rowing boat to find a nice picnic spot on the bank of the river. Hare sees them on their way and wants to join them but there is no room in the boat so Water-Rat tells him to run along the bank alongside the boat and they will meet up when they find a suitable spot.
Unfortunately the threesome in the boat meet up with a family of troublesome ducks on the river. There are 14 of them and they play havoc with Water-Rat, Squirrel and Grey Rabbit, who each lose some of their possessions. They also lose the picnic basket over the side but they manage to rescue it, even though it is dripping wet!
They arrive at a suitable picnic spot and settle down for their picnic. Then Hare decides he will have a row on the river but he meets with disaster as he capsizes the boat and ends up in the river. The naughty ducks then do their good turn and rescue Hare who is told to run home to get dry quickly. Kindly Hare invites them to his house to have some tea and meet his housekeeper, Mrs Webster so they set off in the boat to go to his house.
Once there, they meet Mrs Webster, who provides some lovely food, as they have a jolly time before going home to bed. But as they prepare for bed, there is a pitter-patter of feet and some good news arrives ...
