Walk into Leroy’s Place, in New Orleans’s French Quarter, and a 10-foot hot-pink puppet cat named Casual Carl is the one who greets you, looming under a canopy of fabric trees. The shop is stocked with pun-loving monster art from local makers — a knitted creature called the “Pineapple Hunk” among them — turning a browse for gifts into a wander through someone’s fever-dream diorama.
