Charlie has a little sister named Lola; she is 'small, and very funny'. Lola often gets caught up in situations that she (inadvertently) causes, whether it's running out of money at the zoo and having to borrow Charlie's, to forgetting her entire suitcase when having a sleepover at a friend's house. These situations are sometimes comedic (for example, in the episode 'Help! I Really Mean It!') but often reflect real world problems that younger children may face, for example losing a best friend, not getting the preferred part in a school play, or becoming too excited about an upcoming event and accidentally ruining it. When these situations happen, Charlie usually ends up having to solve her problems through imaginative or creative methods, or by explaining to Lola where she went wrong. This is particularly demonstrated in the debut episode, 'I Will Never Not Ever Eat A Tomato', in which Charlie pretends that her least favourite food (such as carrots, mashed potatoes, fish fingers, and tomatoes) are more fantastical items in order to encourage her to eat them, such as 'orange twiglets from Jupiter' and 'ocean nibblers from the supermarket under the sea'. This may encourage young children to eat particular healthy foods that would otherwise come across as undesirable to them.
