Charlie has to make dinner for Lola, but she's a very picky eater and refuses to eat carrots, peas, mashed potatoes, fish sticks and her least favourite food, tomatoes (although she has never tried these foods before). So Charlie tricks Lola into eating the foods she "hates" by changing their names: Carrots to "Orange Twiglets from Outer Space", Peas to "Green Drops from Green Land", Mashed Potatoes to "Cloud Fluff", and Fish Sticks to "Ocean Nibbles from under the sea".
Lola likes dogs, but can't have one because her parents insist that she is must be responsible enough to have one. Her and Lotta's favourite dog is Marv's dog Sizzles. At the park, the girls persuade Marv to leave Sizzles under their care while he and Charlie go play soccer. However, when they finally get their wish, Lola and Lotta detach Sizzles from his leash (despite Marv telling them never to do so) while fighting over who's in charge, and he goes missing by accident. When the girls finally find the dog, they also see one that looks just like him, and can't tell them apart. They chose the one that sits first (Sizzles' best trick) but aren't satisfied with their pick. Fortunately, Charlie reads the dog's name tag, confirming that he is Sizzles.
Lola has a loose tooth, but does not want it to fall out, until she learns about the tooth fairy, who will leave her money in exchange for her tooth.

Lola finds a spider in the sink when trying to brush her teeth, and she doesn't like spiders very much. Charlie tries to show her that some spiders don't hurt us and that they're our friends. Soon, Lola has grown attached to the little creepy crawly, now keeping him as a pet and naming him Sidney. After they have place the spider outside, the weather changes, and Lola worries on what might happen to her new little friend.

Granny and Grandpa are taking Charlie and Lola to the zoo. But Lola eats all of her sandwiches before lunch, wastes all her bread to feed to the ducks, uses up all of her camera film, and spends all of her money – when she is set on buying a toy seal for the bath. Charlie reluctantly helps her out, but wants her to learn to save things.

Lola is very superstitious and gullible. She hops to bed so some "living sea plants" won't tickle her, sleeps tightly so the bed bugs won't bite, washes really hard behind her ears so mushrooms won't grow there, and turns around three times when she sees a magpie. Charlie quickly regrets it when he tells her not to step on the cracks in the pavement, or else the bears, crocodiles and lions that live underneath will get her.
It is the beginning of Autumn term at school, and Lola finds that everything is different.

Lola is going to Lotta's house for her first ever sleepover, and it couldn't be more exciting. But, little by little, Lola realises everything is a bit different from her normal bedtime.

Lola is sure that she is a good dancer. But some dancing is a bit too swirly, ballet is too floaty, while tap dancing is too shuffly and not tappy enough.

Granny and Grandpa's cat, Caspar, has come to stay with Charlie and Lola. Lola loves looking after Caspar but keeps calling for Charlie's help.
