Create a vertical YouTube Shorts puzzle (1080x1920) in a bright cartoon/comic style. Show two nearly identical illustrations stacked horizontally of owls on a tree. Add exactly 3 subtle but tricky differences between the two images (such as star missing, different wing feather, or branch knot). Avoid making the differences too big or obvious. At the top, include bold, playful text: 'FIND 3 DIFFERENCES!' At the bottom, add text: 'DOUBLE TAP if you spot them all!' Make the scene mystical and calm so it keeps viewers re-watching. See more
