The Madness duck is the undisputed leader of all the [[sanity|insane]] birds((Not to be confused with the [[Chimental|mental]] birds)) in the jungle. ((except for [[mighty_magpie| the mighty magpie]].))((and sometimes [[sugar-hi unicorn| Shi]], depending on her mood)) He is also looked up to as a beacon of the good old ways, and a steadfast role model, by many of the more insane [[monster_list|monsters]] in the [[jungle]].
The Madness duck is:  
  - blue. Except when it's not.
  - mad.((though by [[improbable_island|island]] standards this is perhaps its least remarkable trait.))
  - prone to going QUACK a lot, in a mildly hysterical manner. and then staring at [[you]].((If it quacks three times, it's a different duck altogether))((An altogether more dangerous duck, even!))
  - lethal, even in small doses. Say NO to ducks, kids.


In short, the lesson that all((except those who are now sitting in the [[failboat]], or [[death|dead]])) contestants take from their meetings with the Duck is: if it looks like a duck, and QUACKS like a duck, chances are, you should run like [[hell]].

The madness duck is one of the reasons [[Cousjava]] considers himself mad. That is, Cousjava says that the madness duck says he's mad, so he must be mad.((What, you think you're mad just because the madness duck tells you you are? You must be mad.))
