Cookies

Cookies are, in SuperMarioGlitchy4's videos, a food liked by Lilyncookies and SMG4, Toad, Bullies and Big Bullies.

Lilyncookies
Cookies are one of Lily's favourites foods (not only in the SUPER MARIO 64 Bloopers), but we don't see her eating them in the only video made by SMG4 where she appeared, "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 she ate the bombs, then they exploded in her stomach. Despite this, she still eats cookies non-stop, without becoming fat, and she hates to share them to anyone. For that reason her full name is "Lilyncookies" and her creator's YouTube unsername is "Lilyncookies" rather than "Lily". Maybe the creator likes cookies too.

SuperMarioGlitchy4
According to the video "SMG4 joins the YTR", SMG4 likes cookies, because he accepted to join the YouTube Rangers after Starman3 said him the YTR had cookies. But cookies aren't his favourite food. On October 12, 2013, user Daxter5150 intervewed SMG4, and in that interview, SMG4 said his favourite food was rice and chicken.

Toad
In SMG4's videos (only), Toad 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)". He then comes near people who are having cookies. We don't know if he likes cookies in the real Mario video games.

Bullies
In SMG4's bloopers (but not in real Mario games) Bullies 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
Still in SMG4's videos (not in real Mario games), Big Bullies love cookies as the other Bullies (except Bully Boss (see below).

Bully Boss
Bully Boss is the only Bully who doesn't like cookies in SMG4's videos (and maybe in Mario games too).

Mario
In SMG4's bloopers, Mario apparently doesn't like cookies, as seen in the video "Retarded64: Mario's Spageti Delivary" when he screams "NOOOOOOOOOOOOOOO!!!!!!!!" at The Tubby Custard Salesman (a Po, red Teletubby) when this Tubby asks him "Do you want a cookie?". But we don't know if he really dislikes cookies in the real Mario video games.
