There are a number of collectibles in Tiny Tina’s Wonderlands, one of which is Poetry Pages. As the name suggests, they are pages from some poetry book that you can find hidden in various areas. This page will detail the Poetry Pages that can be found in the Weepwild Dankness area.
Weepwild Dankness Poetry Page Location #1 - Grotto of Sorrows
Head to the Dank Encroachment Fast Travel and follow the path along to the northwest until you see two large mushrooms next to some crystal, then go up the small hill and look to the back right of the area to find a small area you can climb to find the Poetry Page.
