Ana in a barrel is a quest item used by the player during the Tourist Trap quest. It is the result of using a Barrel on Ana, which is used to smuggle her out of the mining camp she has been imprisoned in.
When players go to the equipment menu and check the stats she says "It's rude to ask a lady about her weight!"
Her animation when players talk to her is similar to the Adventurer.
"Taking a turn in the barrel" is a slang term used by sailors which means that it was someone's turn to do a rather unpleasant task, it is possible that Ana in a barrel is an allusion to this.
Ana weighs exactly the same as Zanik, although Zanik is a lot smaller than Ana.
Should players attempt to alchemise the barrel with her, a message appears in the chatbox saying, "You can't do that to the poor girl!"
If players try to teleport while carrying Ana, they will drop her first.
Previously when Ana had been put into the minecart, the examine text for the cart would still be "It's an empty mine cart." even though Ana in a barrel was in it. This has since been corrected with "It's Ana... in a barrel... in a mine cart."
