https://wow.gamepedia.com/Flowerpicker_clanThe Flowerpicker clan was an easter egg in Warcraft II: Beyond the Dark Portal. It was the stored name for the blue orc (Player 2), but since the blue orc slot was never used in a campaign mission as an active player, the name never appeared in-game, though the text string for its title still appeared in the game's data files.
Indeed, unlike the clans in Warcraft II: Tides of Darkness, the Beyond the Dark Portal clan names only appeared in the single-player campaign, and not in custom games. Thus, while the unused Alliance and Horde teams in Tides of Darkness - the yellow team labelled "Horde Traitors" and "Alliance Traitors," respectively - were visible to players despite never appearing in the campaign, the unused blue Horde team's name never showed up without mining the datafiles.
In the mission Dance of the Laughing Skull, the Laughing Skull units produced by the Alliance Expedition are blue, the color of the Flowerpicker clan.
