Truffle (Tuber melanosporum) base form. Truffle Dog never wanted a restaurant. He was looking for a way to stay out of the Kingdom Guards' watchful eye. That required a business front, for his thriving underground 2-methyl-1butanol side hustle. Now you know his secret justification for fabricating the Kingdom's most lavish restaurant. Excessively ritzy, the menu in the window has outrageous prices to keep customers at bay. Passers-by are delighted by the carefully crafted aroma of forest undergrowth, strawberries, wet earth, or dried fruit with a hint of coffee wafting into the neighborhood. A stroke of brilliance. Keeps pigs confused.
