Where's Wally?: The Ultimate Fun Book (Where's Waldo?: The Ultimate Fun Book in America) was a Where's Wally? activity book released in 1990. The book introduces Wilma, her dog Woof, and the Wally Watchers. Unlike the previous three Where's Wally? books (Where's Wally?, Where's Wally Now?, and The Fantastic Journey), this book featured various puzzles and games rather than the traditional detailed crowd scenes. The other kinds of additional puzzles included spot-the-differences, coloring pages, and a board game. The book was also a smaller paperback book that included stickers and press-outs.
