Are these like with Jacques O'Lantern, just a chance to drop from the boss and not a reward? Skittery (talk) 04:16, November 27, 2013 (UTC)

Probably. You get one as a reward from a quest, for the character you're playing. I haven't seen any others drop, but I've only killed it once, so...
A friend said that they're all the same head, though. They phoned it in pretty badly, if that's true. This is what it looks like; (on Krieg. I took the screenshot, but couldn't get the table to work right. ) --Azaram (talk) 02:35, December 2, 2013 (UTC)
It is boring to be collecting the same head for all characters, but I guess that's what you get with the Headhunter packs. The main difference with these is the size for each class. Krieg's I think is kind of awesome. I saw a video of the upcoming skins/heads for Mercenary Day, and they at least varied the facial expressions of the snowman heads.
In case someone looks this up, to answer my own question above, the skins drop from Wattle Gobbler, who can also drop the heads.
