The Wingull Loop-the-Loop request in Pokémon Snap may seem tricky at first, but there's a simple way to make Wingulls perform loop-the-loops on command that makes this request a cinch. All you'll need is an available Wingull, the Melody player, and a little skill with the camera. Here's how to get a loop-the-loop shot of a Wingull.
Wingull Loop-the-Loop Pokémon Snap Request Walkthrough
All the best options for taking a photo of a Wingull mid-loop-the-loop can be found in Beach (Day). A Wingull will appear right at the start of the level, flying right over your head. This may be the best opportunity you get, as there won't be other Pokémon cluttering the frame, and you'll have plenty of time to use the Melody player while it's in frame. This will cause the Wingull to loop-the-loop on command.
After the Wingull flies over you, it will fly over the trees to the left, giving you a wide-open window to shoot it performing a loop-the-loop. Be careful to keep any Exeggutors or trees out of your frame.
Finally, a Wingull will fly low and close to you near the end of the level to the right of the Alolan Raichus.
Once you manage to catch a Wingull during a loop-the-loop you'll receive the Whiskers sticker as a reward.
