Mimi Can't Camouflage

Mimi's school friends love playing hide-and-seek at break time. All of her classmates are great at camouflaging, which means they are great hiders. But no matter how hard she tries, Mimi can't change colours. She's convinced that since she's the smallest in the class, she will never be able to camouflage. Does being small mean that Mimi will always be bad at hiding?
