The clapper for the bell in Big Nate? To get that you must first create the stink bomb in the science lab To create that, add a lot of blue, and then yellow till it turns an ugly green and says eww that stinks(or something like that) If you have bubble gum, chew it in the school and get detention Then place the stink bomb on the floor. Then click on the fileling cabenits and go down Turn on the power by going straight down and clicking Then look around and you will find the clapper.
