David Hunt (born April 11, 1985[2]), known online as GrandPooBear, is an American video game streamer, speedrunner, and creator of Kaizo Super Mario levels.

A Red Bull athlete, Hunt is primarily known for playing and creating levels for Super Mario Maker.

[11] After the 2015 release of Super Mario Maker, Hunt began learning Kaizo techniques from playing over 5,000 hours of the game, including levels created by PangaeaPanga, and created a series of video tutorials on Kaizo game mechanics with walkthroughs of his own levels.

[19][2] Hunt has also appeared at and hosted a number of speedrunning events and other video game tournaments, both in-person and virtual.

He has performed speedruns of both Super Mario Bros. 3 and Super Mario Maker at various Games Done Quick events,[3][4] participated in Fall Guys tournaments at Twitch Rivals events,[20] and performed with other streamers in a recreation of the TV show Survivor in Animal Crossing: New Horizons.

[27][28] Hunt was not the only individual to have levels deleted in this manner, for which Nintendo has received criticism from news outlets such as Kotaku and Polygon.

"[34] On February 16, 2021, streamer TheDragonFeeney released a statement on Twitter accusing Hunt of emotionally manipulating, publicly belittling and sexualizing her.

She identified the instigating moment as a comment Hunt made on stream: "I am angry at Feen that she planned a game without me, because I invite her to everything that I do.

She also claimed that, in 2017, Hunt made lewd comments about her in front of her and her husband, and, in 2018, he grabbed her breast at a speedrunning event.

In Hunt's response,[36] he denied grabbing her breast, and claimed that the lewd comments she mentioned were taken out of context, "purposely manipulating to make me look like some sort of creep."

He also emphasized to his fanbase that he doesn't want this to turn into a "choose sides" war and "make sure that my community - and I understand it is large - does not attack anyone".
