There's something slinking around in Mabel's home. Is it a mouse? Is it a ghost? Nope, it is just the not so friendly and extremely mischievous neighbourhood squirrel. And it is driving Mabel's brother, the neat freak Marcus, crazy by messing up the house. Unfortunately, they can't throw the cheeky little thing out until they figure out a way to save its home - the big tree in the park. Will Mabel and Marcus, together with Julie and Robozonic, be able to save the tree in time? Find out in this book. PLUS: Robodictor explains difficult words in the passage!
