That's like saying you found a Refresh scroll on a Taisai. Just some silly rumor people dropped to mess with people, they teased the Bluebird minion in 2.1 trailer and it seems Pharos dungeon has a mini-boss battle with some giant bird so my money is on it will be in a chest shortly after that similar to the Pudding minion in WP. Every chest we've found in Turn 3 has given x-potions and the like.
