This fantastic follow-up to the Blue Peter Award-winning Man on the Moon, features Simon Bartram's inimitable artwork in an exciting new adventure. Bob is feeling glum - his friends Billy and Sam are off mending a puncture in one of Saturn's rings and there are no space tourists to entertain. He daydreams about a best friend - someone to help with intergalactic missions and jigsaw puzzles. Oblivious to alien activity, Bob also doesn't notice the extra - special dog following him. Could the mono-browed canine turn out to be Bob's longed-for best friend?
