One Too Many: A Seek and Find Counting Book by Gianna Marino

From chapters.ca:
In this boisterous barnyard, the fun grows with each turn of the page. One bouncing flea is joined by two cows, then three horses, and so on, all the way up to twelve swooping bats. Children will delight in following the shimmering path of the flea, counting each bounce along the way to find the new arrival. Older readers can take the challenge further, counting all the animals on the page, or hunting for their favorite. And a surprise ending reveals which animal is just one too many! This frisky hodgepodge is sure to have the whole herd roaring with laughter and pouring over the pages for hours.
