There is a lot of junk laying around the various MS Paint Adventures. Like, a lot of junk. Man you would not even believe how much junk. When dealing with weird puzzle shit it is traditional to pick up anything and everything that isn't nailed down. (And for the things that are nailed down, may we recommend a Hammer?)
Please note that one of Problem Sleuth's more prominent
bugs features is Weapon/Object Duality, which causes seemingly harmless objects to spontaneously transform into horrific weaponry. In such cases we have placed the harmless and deadly versions of an item on the same page to avoid confusion.
That's the thing about us MSPA fans, after all; we loathe confusion.
