Beans are root and white? I guess you are still dreaming. ;)

But I already feared that most people outside of Europe won't know the tale I was referring to.

I'm admittedly rather confused to that one myself. I'm curious if you could tell me in chat or tell everybody after a4plz guesses it.

Check your chat for an explanation. And be warned: My next hint might be even more obscure. ;)

Oh, that kind of beans. I was only thinking of green beans. It's obviously me who is still sleepy.

Those are the beans I imagine when I think of Jack and the Beanstalk, but you must be thinking of a different fairy tale. I've got some root vegetables to google.

Clue #4: Leaves

Artichoke?

No.

Ok, here is a very obscure hint. I wonder if you can figure it out.

Fifth clue: Keutschach

My finger was already hovering over this one, but now I'm pretty sure it's... a Turnip!

That's correct! Congratulations!

Congratulations to PaterAlf & a4plz.
Our password was celery, also the next clue I was going to give was Hypocotyl.
Thank you Puzzlemaster for a great game.

Erm...it's....not....over.....?
Like, I was going to give them a new clue and have you guys continue on your current one....

Unless of course you don't want to play any more, in which case I could start things over from scratch and swap in Maxvorstadt.

Thank you, but it's not over yet.

"The first team to guess 5 passwords wins."

You don't get away that easily. ;)
I think you should give new passwords to both teams and let team 2 start this time.
