This hidden-object puzzle takes place in a bowling alley. The cartoon is easy to understand at first, but the final item is meant to slow you down. Your challenge is to find all four objects, especially the hidden whistle.
Before checking the answer, take one more careful look at the picture. Do not only search for objects sitting plainly on a table or floor. In these puzzles, the hardest answer is often disguised as a seam, fold, stain, shadow, branch, or background line.

Good hidden-object cartoons work because the answer feels obvious only after someone points it out. The object is not missing, but your eyes may read it as part of the room, furniture, clothing, or scenery. That small moment of visual confusion is what makes the puzzle fun.
Here are all four answer locations:
- Bell: as a small icon on the scoreboard.
- Coin: on the red bench.
- Sock: inside the bowling shoe.
- Whistle: on the blue bowling ball, where the shine and finger hole form a whistle-like shape.
The 4th object, the whistle, is the trickiest one. The whistle is camouflaged as bowling ball highlights and holes rather than drawn as a loose item. Once it is circled, the shape should make sense, even if it was easy to overlook at first.

If you found it without help, that is a sharp-eye win. If you missed it, do not worry. These puzzles are designed to make the brain look twice. Share it with a friend and see whether they can spot the hidden whistle faster than you did.
