User relic724 started a guide that lists all the Thing stickers in the order that they're numbered in the museum, along with short descriptions of where to find them in the environment, attack info, and repurchase price. A few of the items weren't there, however, so I took it upon myself to fill in the missing pieces. Other than maybe adding more detailed descriptions of where to find the items, the guide is essentially complete. Please look at it before making topics asking which Things you're missing and where to find them.
I'm planning on making a similar guide for regular stickers, so stay tuned for that.
