Children's animation. Charlie loves his little sister Lola, even if at times she can be infuriating! Lola doesn't like the hat that Lotta gives her. It's itchy and it has 'dangly bits'. Even Soren Lorenson, Lola's imaginary friend, thinks it wouldn't be too bad if she lost the hat by accident. It's only when she really does lose it that Lola realises her friendship with Lotta is more important.
