Cookies

Cookies are, in SuperMarioGlitchy4's videos, one of the favourite foods (or the really favourite food) of Toad, Lilyncookies, Bullies and Big Bullies.

Toad:
He likes cookies, which results in Toad turning occasionally into Cookie Monster (the friend of Elmo from Sesame Street) screaming "COOKIE!!", as seen in the blooper "Ssenmodnar 6 (New Year's Edition)".

Lilyncookies:
Cookies are one of Lily's favourites foods, but we don't see her eating them in the only video made by SMG4, "Ssenmodnar (1,000 subs special)". In MarioMario54321's videos, she often appears when someone is talking about cookies, and she once has eaten a whole mountain of cookie in a vault. She is so obsessed with them that she once has mistaken Bob-ombs for cookies when she was walking with Mario in Bob-omb Battlefield, and the bombs exploded in her stomach. Despite this, she still eats cookies non-stop, without becoming fat, and she hates to share them to anyone.

Bullies:
They love cookies, as Toad and Lily, and they run towards every cookie they see. In the blooper "Boil the Big Bully", they're watching the video "Ssenmodnar 6", where Toad turns into Cookie Monster screaming "COOKIE!!" when he sees a sign near Princess Peach's Castle saying the Dark Side has cookies.

Big Bullies:
They lovee cookies as the other Bullies (except Bully Boss (see below)).

Bully Boss:
He's the only Bully who doesn't like cookies in SMG4's videos.

Mario:
He apparently doesn't like cookies, as seen in the video "Retarded64: Mario's Spageti Delivary" when he screams "NOOOOOOOOOOOOOOO!!!!!!!!" at Po (the Red Teletubby) when this Tubby asks him "Do you want a cookie?".
