The chef was a gnome that appeared during the 2013 Thanksgiving event event. He gave players cooked turkey when asked for food.
When asked why he's there, he said "Why, we're having a feast. I'm cooking while the kids have some fun with the gnomeball net." If spoken to with two turkeys in the player's inventory, the player would immediately ask the "Why are you here?" option, followed by ending the conversation with the "Cheers" option. There was no normal way to get more than two turkeys at a time.
