Professor Knacks' Invention Goes Wild

Professor Knacks has invented a new machine, but he has made a mistake – and hey presto, it has made off and is causing all sorts of chaos. The zebra crossing is aglow in all the colours of the rainbow, a shark is swimming in the fountain, and since when have cactuses been able to fly?

More than 250 crazy mistakes are waiting to be discovered. The tricky search furthers concentration and logical thinking and is tremendous fun!
