It is a freezing day in the park. Soon the snow does begin to fall, and fall very heavily. The weather reports warn of heavy snowfall and strong winds, advising everyone to have their hot water bottles to hand.

Percy is very busy with all his work around the park, and does not have time to play with the animals, who are bored and looking for someone to have fun with.

Percy is having a day off and is busy making sandwiches for a picnic. The rabbits are frolicking in the park and the youngest is being a bit too reckless. She tumbles down the hill and lands on Percy's doorstep. He tells her that he is having a picnic and then warns her to "Look before you leap". She bounds off, barely heeding his words, more excited about telling the other animals that there is a picnic!

It is a bright Autumn day and all the animals are playing in the fallen leaves which Percy has been trying to sweep up!!! He tries to get them to tidy them up again, but they make even more mess. Eventually, though, they finish, but it begins to rain. Everyone says goodnight and hurries to their tree, except for Squirrel, who has moved out due to the noise Owl has been making.

Hedgehog is very upset. He loves balloons but he can never keep them because they always burst on his spines. Then Percy comes up with an ingenious plan, and with the help of some corks from his garden shed, the problem is solved.

Squirrel tells Fox a rather funny joke, which gave him the hiccups because he has been drinking lemonade. The others try to cure him, but out of them, Owl only succeeds, which then gave her the hiccups!

It is winter, and very, very cold. So cold, in fact, that Fox borrowed some of Percy's clothes with the help of a scarecrow in the cold winter night. Percy doesn't notice though, because Fox puts them back in the morning.

Rabbit has become afraid of the dark, and the others don't know what is causing it, but Percy does - she hasn't been eating enough carrots! She then eats some more, and is then able to see in the dark, and is not scared anymore.

Percy is taking the day off and builds a sledge. However Fox and Squirrel borrow Percy's materials to make their own sledge. Then they offer Percy a ride in it.

It is a rather windy autumn, so Hedgehog sneaks into Percy's garden shed and borrows his tools to build himself something to fly with - wings. But he then soon discovers that flying is quite frightening indeed.

Owl discovers a little bird who doesn't know how to fly, so she attempts to teach him. Then Percy comes along and explains he can't fly because he's only little, which Owl doesn't know.

Badger spends a long time digging, getting himself dirty. Percy tries to give the badger a bath, but he doesn't want one. As Percy has the bath to himself, Badger falls out of his hiding place into the bath tub.

When Percy catches a cold, Owl offers to help make a rake, plant a tree and paint the roundabout. But she isn't very good at remembering and gets them all muddled up.

As Badger and Fox help Percy tidy his shed, Mouse joins in the work, but her clumsiness isn't helping. But when the trio become trapped, Mouse proves to be very useful to them.

Percy uncovers a treasure map and he and Squirrel go and find the island it was buried in. They do find it eventually, but Percy then remembers he left a fruitcake inside the oven, and goes back to his hut, leaving Squirrel not knowing where he is.

Winter is approaching, and Old Rabbit wants to sleep for a while, but the mice are disturbing him with their fun and games. Percy persuaded the mice to play elsewhere, but the peace doesn't last for long.

Percy plants some bulbs under the ground. Unfortunately... Squirrel has lost all her acorns and mistakes the planted bulbs for possible acorn storages. Mole finds his secret storage by accident and the squirrel replants the bulbs.
