alright I whipped up an idea, in the laundry room there could be a sheet item, (like bed sheets) you may only carry one, but you may tie the sheets together if another player is standing in front of you and clicks (or you click) now with tied sheets, here are a few ideas on what you may do with them(just some ideas for mechanics)
tie one of the sheets to your teammate's legs, and use them as a lure/scout for towers/dog, just right click to tug him back in at a fast pace; the more sheets, the farther he may go.
unfolding the sheet over say a window may obstruct view, as long as the two distances between where youre tieing and nitching the two sheets to spread out isnt too great, this could be neat for some cover.
on combining items, you could use the sheets on two laundry carts in order to form a little sling shot launcher, or tie it low and tumble the dog (revenge)
idk it was just an idea lol
