Haggler's Junkyard consisted of a storage shed, and a shop. The shop was where he sold items that people brought in that they didn't want anymore. The shop played a large role in #690: “The Green Ring Conspiracy, Part 12”. Wally Haggler, the owner, allowed a club of tinkering boys, The Square One Club, to meet in a building there to take things a part and figure out how things work. It contains all sorts of items, which is one reason the Square One club liked to hang out there because it gave them all sorts of opportunities to take apart different things.
