<sup>I marked this as community wiki for a reason. Please feel free to edit it with images, more information about a hat, or anything else.</sup> # Chameleon Chameleon is tricky. It is currently unknown _exactly_ what the trigger for it is, but it includes editing your profile. The current theory is that you are randomly assigned a name of a profile field (e.g. About Me, Website, Location). Editing that specific field will give you the hat. Things that have been known to trigger the hat: - Editing only Email, Profile Picture, Birthday, Display Name, Location, About Me, or Website. - Editing multiple fields, including About Me and Website. - Creating a new account on a site, i.e. attempting to log in on a site you have not created an account for, and then clicking "Confirm And Create This Account" However, there have been many cases where making the edits mentioned above did _not_ result in the hat being awarded. ---------- # Eureka Eureka is manually awarded by the Stack Exchange staff to users who independently guess exactly how to get any secret hat. ---------- # Fascinating Fascinating is earned by upvoting an answer that is accepted and has a score of at least 5. ---------- # Fascinating, Ma'am Fascinating, Ma'am is earned by upvoting a question that has a score of at least 25. ---------- # Hairboat Hairboat can be earned by commenting on one of [abby hairboat][1]'s posts. ---------- # Time Lord Time Lord can be eared by editing 5 old questions. It is unconfirmed how old the posts have to be, and whether it can be earned by editing answers. ---------- # Waffles Waffles can be earned by voting on a post, editing it, and then changing your vote. It is unconfirmed whether is it possible to earn it by changing you vote after someone _else_ edits the post. ---------- # Warm Welcome Warm Welcome is earned by upvoting a new user's first post. It is unconfirmed exactly how new the user has to be. [1]: http://meta.stackexchange.com/users/165581/abby-hairboat
