Riddle badge.

chara is that you?

how to get:
first you need to go to noxy's room in the house3 map then you gotta find a small pillow. once you found it. throw the pillow away and grab the catmint under it. go to the room with the black carpet and dark grey walls. put the catmint at the forcefield square. once the layer got disabled. find the other catmint hidden near the large garbage disposal. if you found it. it will be hidden near the house pillar. grab it and do what you did with the other catmint. the last catmint can be found at the right top side corner of the map. once you grab it. bring it back to the grey room and put it on the forcefield square again. once you did that. the layers of the hole will be open. jump into the square hole and you will get the badge. if you want to get a better explanation. search it on youtube. the grey room sometimes changes color whenever the map changes. the image shown here will help you enough to find it.
