Firstly, I really liked the overall concept of this object and it's application, but I do have one question: what are Smile Canisters? I mean, I did kind of understand from the author's explaining about it, but I am actually wondering if it has been cited in other levels/tales/etc., because I tried to search about them and it seems they have not been talked about in any other place.
So, did the author of this object think about the Smile Canisters, has it been referenced before and I am just no finding it, or did it exist and, for some reason, it was removed from the wiki?
Don't worry though, I don't think not knowing what Smile Canisters are really affects the overall comprehension of the object.
