A complete guide with pictures to everything required for the “Cosplayer” achievement, including all Photo Challenges.
Introduction
Since getting this achievement absolutely requires the completion of all the Photo Challenges I included instructions on them as well rather than simply pointing out that you have to do them, in order to make this guide more comprehensive. The only things required for this list that are not detailed in how to obtain are the horn attachment for your camera, the log removal quest and the power plant fixing quest, since these are almost unavoidable while playing.

Oaklaville




03 – Fjällbjörn Hat – East of the hotel you’ll find the Scout House, and next to it a kid who’ll give you the “Become a scout” quest. You now have to hunt for three specific items.




04 – Ghost Glasses – Keep going west after the mushroom house until you run into a building next to some gravestones. A skeleton man will come out and give you the glasses immediately.

05 – Soaked Sock – First talk to the guy sitting next to the hotel for the “Missing socks” quest. Then go to the benches near the Mushroom House and equip the ghost glasses. You’ll see a ghost there who’ll ask you to compete on a game of “find the sock”, which is a simple “find the ball” game, where he presents you with three cups, hides the socks in one of them, moves them around and has you point out which one you think has them. It’s quite slow and easy the first time, which is all you need (though you can keep playing if you want another stamp). Once you get the wet socks, go give them to the sock guy and he’ll take just one, leaving one for you to wear.


06 – Foam Finger – Go behind the hotel. There’s a gift box there, containing the item.

07 – Monster Mask 1/4 – Bushy – First, enter the hotel and talk to the boy there to get the “Monster spotting” quest. You’ll have to find four monsters. This quest encompasses four maps and as such it’ll be the longest of them all. The actual steps to do it are very simple, you just have to wait until you reach the necessary places to do them. The first monster is right here in Oaklaville.



Photo Challenges – There are 8 total photo challenges. Two for each map (save for the first and last), with a total of 16 pictures to take. You need to complete them all to unlock the last item. This will be the most time-consuming part of the achievement, but there’s no quest attached to it.
Photo Challenge 1:
– Mossy Rock and Pine tree: these are both right on the screen where the kid gives you this quest. You might easily get them both in the same picture.
– Axe: You find this one on the same screen with the Scout kids.
Photo Challenge 2:
– A tiny army of soldiers: On the same screen where you get the Photo Challenge 1, near the quest giver there’s a bunch of ants walking around. Take a picture of them.
Stanhamn











Monster Mask 2/4 – Lochy – Near the farmer stand-in picture cutout and the hippo lady, there’s a disturbance in the water. Set the tripod nearby and walk down to the beach. You’ll hear a splash. Activate the tripod and you’ll be able to take the monster’s picture.


Photo Challenge 3:




– Become a farmer: On the screen with the hippo lady there’s a farmer stand-in picture cutout. Take your picture in it with the help of your tripod.


Logcity




Monster Mask 3/4 – Sewy – On the area with the skating kids. Position the tripod near the manhole and get yourself near the workers resting. Once you hear or see the monster getting out of the sewer, take the picture.


Photo Challenge 5:







– Critical confusion!: On the screen west of the Hotbean Bros. kiosk there’s a guy standing next to a parked car, confused about getting a ticket (you can see question marks popping out of his head). Take his picture.

Kiiruberg







Monster Mask 4/4 – Tally – On the screen east of where you find the balloon kid, where the wind is stronger. Position the tripod near the claw marks on the cliff and hide behind the hill (you’ll have to break the large ice barrier with the horn). When the monster shows up, take the picture.



Photo Challenge 7:
– Moon: Very simple. Just point to the sky in nearly any screen.



– Wall of lights: Take a picture of the large server inside the Observatory.
