Where to get these Holiday heads and skins?

so I know that the humanoid head are from the tell tale series bonus content to season pass holders, now the snowball was from a headhunter pack" marcus mercenary day" an the turkey was the same from the “wattle gobbler” . now its my understanding that this game is made with bl2 codes so someone may have “imported” the head into tps . then they gave it away… or fingers crossed here, but maybe there is some holiday dlc in the pipe for tps . but sadly my $$$ is on the prior.

They look like legit heads and skins though
