I'm looking for a particular kind of die - a six-sided with a happy face, an angry face, and a neutral face repeated on it. D&D players will know what I mean. Except I have NO idea what it's officially called, and I can't find it anywhere online. I've searched for "happy dice" and all variations of the phrase, including checking the Wizards website and eBay, but no luck.
Where can I find a place that sells this elusive die?
