Webbed

Tucked on the right side of the map is a hidden skatepark that can be accessed via the Bee area or the Ant area (out of the 2, it's much easier to get there through the Ant area since that section doesn't have nearly as many alternate paths - you get there through the housing area).
 

 

When you enter the area, you'll meet the dopest skater in the gaming world, the infamous Skatebird! When you talk to them, they'll ask you if you're ready to shred and show the world what you got. You'll get a skateboard and then be sent on your merry way. In the middle of your screen will be the word "WEBBED" in grayed-out letters. Floating around the skatepark will be the letters required to fill in the word. You just need to touch each letter to pick them up but only if you are on the skateboard. You can use your webs to move around if you need be but make sure you're holding  so you're gripping onto your board at all times. If you fall off or it goes flying, you'll need to retrieve it. If you can't find it, just talk with Skatebird again to get a new one (though do note that doing this will reset your progress with the letters). The letters are all in plain sight so just make your way through each layer of the skate park to get them. Once you've picked up all 6 letters, you'll be rewarded a sticker (required for Collector ) as well as this trophy.

If you don't get this on your initial playthrough, you can get it after you've completed the story and are back home with your boyfriend (you'll be put into a free roam session of the game).
