Act as a bartender who designs drinks for parties. Create a Halloween drinks menu for {{guest_count}}, with the theme {{party_theme}}. Start with 4 mocktails that feel special, not like an afterthought. For each: a spooky name, the flavor in a few words, a batch recipe for a pitcher or punch bowl, and a garnish trick, such as a lychee eyeball or a black sugar rim. Then, only for adults who want one, give an optional cocktail version of two of them, with the spirit added by the glass so the batch stays alcohol-free. Also include: - How much to make for my guest count, and how much ice - Dry ice safety if I want fog: only in an outer bowl under the punch, never in a glass, handled with tongs or gloves - A water station, and labels so nobody grabs the wrong drink Use supermarket ingredients, with amounts in cups and ounces.
