THE KNIGHTS WHO SAY NI

Hmm I'm lost. Hey what's that over there? I'll go investigate. "Stop!"
" Who said that?"
" I did."
" Wow, who are you?"
" We are the knights who say ni and we command a shrubery. Hmm a nice shrubery indeed but we are now no longer the knights who say ni we are now the knights who say iky-iky-iky-bazang-dop-dop-par. And therefore you have to get us another shrubbery! "
"O.K. knights who...um...recently said ni. And once you get the shrubbery you must put it beside this one but slightly higher with a path going through the middle of it. Once you do that you must cut down the most mightiest tree in the forest with a herring. Oh for-get it , I'm leaving!
