Skulle hjärnväggens Extract Brain påverka polymorphed eller Wild Shaped humanoids?

Ett mind-flayer har följande krav för att utföra sin Extract Brain Action (MM, 222):

one incapacitated humanoid grappled by the mind flayer.

Om en humanoid har blivit polymorph ed (PHB, 266):

This spell transforms a creature that you can see within range into a new form...

The target's game statistics, including mental ability scores, are replaced by the statistics of the chosen beast. It retains its alignment and personality.

Om en humanoid har använt Wild Shape-klassfunktionen, de (PHB, 66-7):

magically assume the shape of a beast that [they] have seen before.

Your game statistics are replaced by the statistics of the beast, but you retain your alignment, personality, and Intelligence, Wisdom, and Charisma scores.

You retain the benefit of any features from your class, race, or other source and can use them if the new form is physically capable of doing so.

I båda formerna är varelserna klart odjurliga, men är de (eller deras hjärnor) fortfarande ansedda som "humanoida"?
