Welcome to Spot The Difference - Outer Space! See if you can spot what's different in 15 out of this world puzzles! Each double page contains two scenes that are almost identical - all you need to do is search for what's changed; a planet might've swapped color, a rocket could've lost a window... or an alien could've gained a leg! A great, interactive book for little ones who love to puzzle solve, ideal for rainy days and car journeys.
