Timmy accidentally kicks a football through the nursery window! After a stretch on the naughty stump, he tries to be more careful, but ends up knocking down Otus' sandcastle with a careless kick of the ball. After much soul searching, Timmy realises it is not enough to say sorry, you have to show you're sorry too.
Timmy has lost the last piece to his jigsaw puzzle. But wandering the nursery to find it, he discovers other lost toy pieces. Returning these to their rightful boxes but failing to find his jigsaw piece, he sadly begins to pack up the unfinished jigsaw... until his friends find a certain lost item for him!
Timmy dreams of being an explorer who tracks and photographs wild animals. He sets out to search around the nursery with his camera. He is so disappointed when there aren't any exciting animals to be snapped, that his friends decide to give him a treat: they dress up as wild animals so Timmy gets the shots he was after.
Timmy's new friend is big, round, friendly and very, very bouncy. It's a space hopper. Timmy tries to involve his new pal in his nursery day but it is very awkward and keeps causing accidents. It's only when Harriet confiscates the space hopper that Timmy works out what it's really for: loads of bouncy fun!
Stripey plays at dressing up and by accident ends up looking just like Timmy, with a white woolly waistcoat on and floppy black socks on his ears. Timmy is delighted to have a twin, Stripey is too. Timmy makes Stripey a lamb's tail to wiggle and a twin teddy to complete the look. But although he looks like Timmy, Stripey isn't much good at being a Timmy twin: he can't baa, his tail wiggling leaves a lot to be desired and he's terrible at football. During a game of football, Timmy gets impatient when Stripey keeps missing the ball so he passes it to his other friends instead of to Stripey. Stripey feels left out and trundles off sadly, taking off his costume bit by bit as he goes. Timmy realises his friend is upset and has an idea: he dresses up as Stripey much to the badger's delight and makes Stripey noises with a horn.
Timmy's imagination is sparked when he reads a superhero comic. Meet Super Timmy! Timmy is desperate to save the day but his efforts aren't always appreciated. He 'saves' Mittens dolly from the seesaw, but Mittens was just playing; he 'helps' Otus with the gardening but accidentally soaks him with a hose pipe in the process; and he heroically tries to stop Yabba getting muddy, when that's exactly what Yabba wanted to do. Finally, Super Hero Timmy gets the chance to save the day when his little pal Bumpy is nearly splattered by paint. Hooray for Super Timmy!
Harriet is doing odd jobs round the nursery and Timmy is eager to help out. He finds a yellow beret (the closest thing he can find to Harriet's yellow hard helmet) and a toy tool belt and begins his round of odd jobs. Unfortunately his attempts at mending his friends' toys result in disaster: a wheel falls off Mittens' hobby horse, Ruffy's robot breaks and Ruffy's remote control car just grinds to a halt. Finally Harriet takes matters into her expert hands, and together her and Timmy make amends. Timmy learns how to mend things the right way with the right tools, and Harriet rewards him with a proper yellow hard hat of his own.
After a fun playtime activity of making a model castle, Timmy's imagination is all fired up. He wants to play at being Timmy the Knight, encountering dragons and saving Damsels in Distress. Along with Finlay, he dresses up as a knight and together they clippety-clop around the nursery on their trusty steeds - a customised broom and a hobby horse - and carry out several chivalrous deeds. The play acting bug takes over the whole nursery when together the pals all make a wonderful castle of their own out of big cardboard boxes and they all dress up. Timmy and Finlay's chivalrous spirit is put to the test when the friends hear what sounds like a real dragon.
All the nursery pals are putting together scrapbooks of their most precious childhood memories: their first tuft of wool, photos of them as babies. Timmy ends up with one blank page left in his book and he's on a mission to find something perfect to put in there. All his attempts fail: the jam sandwich splodges and makes a mess, his self portrait sculpture gets squished and the football just won't fit in no matter how hard he tries to shut the book. Finally, the scrapbook is in tatters and the disappointed Timmy gives up. His friends cheer him up by putting together a new scrapbook. And Timmy repays them by having the idea for a group photo they can all put in their scrapbooks.
