Thirteen-year-old Eclair used to occasionally scavenge outside, but after getting shot in the foot, he was out of commission for a couple months. During that time, he managed the food, using the scraps of cookbooks he found while scavenging with passable results. He does an excellent job with the cave fungus that makes up most of their food. He occasionally tries to create more elaborate food from his cookbook scraps, often with disastrous results (hence his nickname).
He wears a ragamuffin tophat, the only one in the base game, and one of the only two with Point Lookout installed. Kenny wears the only other one, in Point Lookout.
Eclair spends most of his time behind a counter in his restaurant, "Spelunkers" in Little Lamplight. He can also sometimes be seen around the restaurant when there are no other non-player characters in the area.
Unlike most merchants, Eclair's shop key is on his person, instead of only appearing after a the merchant's death(which is not possible). His merchant container is also unowned. Given these conditions, obvious opportunities for theft present themselves.
