Oliver Pie and his mum and dad have moved into a new house.

Down in a corner of the garden, Oliver finds an old stone statue of a Griffin - he starts to talk to it and to his amazement, it replies.

The statue is rather grumpy - he was made to be a Guardian of Hidden Treasure, but now he is abandoned and covered in weeds.

Oliver gets to know the Griffin and they become friends, but then one day Oliver comes home from school to find Dad has sold the Griffin to the local garden centre ...
