Boyface and the Quantum Chromatic Disruption Machine

Boyface Antelope has been waiting his whole life to turn ten and be allowed to enter his parents’ stripemongering shop. On the morning of his tenth birthday he finds his parents ill, and they ask him not just to go in the shop but to look after it on his own! His friend Clootie has also turned ten today, and has also been waiting to enter the shop. Between them, will they be able to handle the delivery of five irritable tigers and keep the stripemongery running smoothly?
