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.
