In Circhester, there are 2 hotels. Enter the one on the right. To get to the floor, go into the elevator. If you enter the first room on the left, and cutscene will play about finding the culprit of the hotel’s berries. You have to solve the mystery. Talk to all of the suspects and then one of the suspect’s Skwovet will appear. Talk to it twice, and say it’s the culprit. The detective will award you with the Wide Lens.
Hope this helps! :)
