Thomas and Percy have been given a very important job: to deliver ten cows to McColl's farm. 

It sounds like an easy enough task, but when the cows start to disappear, Thomas and Percy must search all over town to find them.  Join Thomas and Percy on this counting adventure - can you work out how many cows are missing on each page?
