I have 21 effects so far and I saw this shirt in a closed off room. I thought it was reminiscent of the locations the humans send you to, so I tried to figure out which human would send me here, but when I finally managed to figure out how to get here, touching the item just tiles its image everywhere. I've tried touching it with certain effects but going through all 21 would take forever. So is this an item, and if it is, does it rely on using a particular effect? Or have I just wasted my time?
