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.

A treasure hunt with painted eggs! But Timmy's is nowhere to be seen. Harriet helps Timmy to search but even she cannot find where she hid his egg, so she encourages Timmy to forget about that game. Finally Timmy reluctantly joins in a different game and, lo and behold, he finds his egg.

It's dressing up time, and Timmy gets to play Doctor but he won't take his costume off and insists on treating his class mates as patients. But when a mysterious case of spots breaks out during Art Time, his friends turn to Doctor Timmy to find the cure.

Timmy and Kid are obsessed with triangles. Nothing else will do. Art, food, cushions - everything must be three sided. Until, that is, they attempt to build a tower of blocks and race a toy car with triangular wheels. But no matter! For Timmy, triangles are so over. Now only circles will do.

Timmy is fascinated by the Moonscape collage that he and his friends make - especially the little green aliens that live on the moon. Finlay notices this, and with Harriet and Osbourne's help, he gets his friends to trick Timmy into thinking that aliens have landed at the Nursery!

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!

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.

Timmy and Yabba make a fire engine out of an old cardboard box.

Yabba is distraught when Timmy manages to let her balloon go flying off into the sky. His various attempts to make replacements do little to cheer her up, until he spots Bumpy hanging from the balloon's string as it bobs around the Playground.

Harriet and Timmy come up with a plan for Timmy to give a very unusual performance

It's Music Time, and Timmy is fascinated playing the xylophone. When Play Time comes, he insists on taking it with him, but drops it and one of the chimes is lost. He tries some crazy alternatives with no luck, until he hears a strange chiming noise coming from Paxton on the see-saw.

Timmy and Ruffy are so tickled when they discover the fun you can have with squeaks that they accidentally spoil Otus's big moment in a musical lesson. They feel very bad and make it up to Otus by devising a totally new squeaky musical performance for him to provide the finale to.

The class make a Chinese dragon and Timmy wants to be the head. But it's Finlay that gets that honour, much to Timmy's disappointment. Until that is Timmy realises that there's another part of the dragon which is as special and essential and just as much fun - the tail.

Timmy and Otus build a kite, but Timmy's excitement and impatience cause chaos.

Harriet shows the class how to make cookies and Timmy decides to make one bigger than all the other cookies put together. He then decorates it as a football, and spends the day trying to protect it from being trodden on, eaten or broken.

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.

Osbourne replaces Timmy's broken trike hooter with an even bigger, louder one

Mittens is playing Mummies, and wants Timmy to be the baby in her make shift pram. At first reluctant, Timmy soon finds out that being a baby can be fun especially when everyone spoils you rotten! But when he finds that babies don't play football, his enthusiasm starts to wane...

Osbourne shows the class a new super rabbit toy, and Timmy is thrilled to be the first to play with it - but his friends also want to include it in their less than super heroic games, so Timmy has to try and find a way to keep everyone happy.

Timmy is enthralled by Mittens's new music box which has a splendid ballerina on top. But he and Yabba manage to break her precious toy, and despite their best efforts to replace it, Mittens is inconsolable, until Yabba persuades Timmy to play the ballerina himself.

When Timmy's glove puppet goes missing, he creates chaos as he hunts for it, digging up the sandpit, searching vehicles and frisking his classmates. But there's no sign of it and Timmy is about to give up until he gets a big surprise when Snack Time comes.

Timmy thinks Otus's Jack-in-the-box is brilliant, and he decides to make his own. But it's not as simple as it looks, and after several failed attempts Timmy gets an idea of how he can make the best Jack-in-the-box of all.

After a muddy ride around the Playground, Osbourne shows Timmy how to clean his tricycle.

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!
