Maybe to terminate that silly string Spam you talked about maybe there can be command like /clearsillystring and having the Pizza would be cool OOOOOO
maybe that soda spray thing (like in that spongebob squarepants episode where patrick and spongebob stops being friends but turns to squidward to be their friend and at the end they are having soda) when you shoot someone with it they fly to what ever direction it hits them (for humor)
