Robert the Rat

All Josh can think about is the pet rat he desperately wants for his birthday. Toby at school has a rat, so why can't he? But Grandad wants to get him a metal detector like his own. It's embarrassing enough having to dig holes at the beach for Grandad, let along go scavenging himself. They never find anything but junk anyway. No, a rat is the only present he wants. But there's one little hurdle to overcome first, Mum cannot stand rats. First person recount. Suggested level: primary, intermediate.
