Draco's Monster Skin Series - Bog Poison Pukei-Pukei is an add-on for Monster Hunter World that lets you change the skin of the Pukei-Pukei to look more like a poisonous dart frog. The idea behind it is that a Pukei-Pukei looks more poisonous to the eye when it's skin is green. It also allows you to keep the skin of the Pukei-Pukei looking the same way even when you change the colors of the rest of the creature.

To install this add-on, you need to extract the files from the RAR you downloaded and then install them into the Monster Hunter World application. Once you've done that, you're good to go! To uninstall, just delete the files that were put into the Monster Hunter World application according to the instructions that you found inside the RAR.
