Max loves animals, but his sneezy, allergic sister means no family pets.

He's so happy when he realizes he can be a pet sitter.

But with every job he takes on, there's always something a bit odd about his new boss.

Witches, fairies, goblins, mermaids - why can't he pet-sit for someone ordinary?

Max is minding his own business one day when an urgent call comes through from Ivor Gadget.

Max has to pet-sit his dormouse, Dixie, for three days while Ivor collects a spare part for a new invention.

Ivor is hardly out the door when Dixie escapes her cage - little does Max know that a chase beginning in the living room will end up 2000 years away . . .
