One, two three. One, two, three. Why wont someone play with me? Heidi is a stick insect, long and thin like the twig of a tree. It is her first day at Bug School, where she hopes to learn lots and make new friends. But no-one will talk to her... and no-one will play with her at lunch. No-one even notices her! Perhaps she is blending into the twigs a little too well? Luckily, Miss Orb comes up with a plan to help Heidi stand out.
