The I-Spyder Book of Earth Creatures

The I-spder book of Earth creatures is an electronic book it looks like a slim plastic slab. It lists evry animal on Earth there has ever been. The book states the amount of points you get for each animal you spot. When you have spotted enough creatures to gather 9 million points Big Cheif I-spyder sends the person a certificate. Martha manages to gain this certificate in the events of The Last dodo by going to the Museum of the Last Ones. Time Lord gives the most points even though it is not from Earth.
