Press the flag and the dingus duck "asks" for some chicken strips or "chiken stips". The goal is to make the dingus as mad as possible. To do this, simply type "no". When you trigger his anger, he says "hOw DaR u GiV nO cHiKeN sTiPs aM cALLiG cOrPrEte" which also makes him start spinning uncontrollably and change color infinitely. Sorry, dingus. No chiken stips for you.
