David Hunt is a game streamer on Twitch.tv and a YouTube userYouTube who goes by the name Grand POObear. His name has several origin stories. He's told people tales ranging from having a Childhood friend named Christopher Robin to meeting NBA star Pooh Richardson. ^{[11] [3]}

Hunt wanted to be a professional snowboarder and was working towards that dream, competing in tournaments, waiting tables and giving snowboarding lessons. Tragically, he was sideswiped by a novice skier and suffered some horrendous injuries—a broken kneecap, a torn MCL, a fractured L1 vertebra. The worst part of it though was the damage to his spleen. He wound up with abscesses and a salmonella infection that required emergency surgery and left him bed-ridden for over four months. Hunt went from weighing 165 pounds to a meager 105. ^[18]

While he was holed up and unable to walk, Hunt started playing Super Mario Bros. 3 and quickly found that he has a knack for hyperfocusing and speedrunning video games. David set up a Twitch streaming account during this time and the rest is history. Hunt has used his platform to support charitable causes, coordinating Mario Masters Colosseum, a four-day game-a-thon that gathered a dozen speedrunning stars to raise more than $100,000 for Direct Relief, a nonprofit that provides medical services to the poor. He also used his talent to fundraise for Doctors Without Borders and the Prevent Cancer Foundation. In 2018 a twitch viewer named the_kobold_inn gave him $4,000 as a reward for doing so much good. ^[19]

Video game developer BarbarousKing has created two installments of near-impossible mario levels called Grand Poo World and Grand Poo World 2.

Hunt's speedrunning prowess has landed him a sponsorship deal with Red Bull. ^[19]

In February of 2016, Hunt made news when he and some other gamers who had spent insane amounts of time creating levels on Mario Maker saw their work vanish into thin air. The problem was especially distressing because Mario Maker made up much of his streaming content, he said: ^[10]

Customer service was unable to figure out why the levels were deleted.

In January of 2016 he had a similar problem when trolls had reported one of his levels and successfully had it removed because of a "poo" related name.

In 2019, Hunt had another one of his levels deleted when it was flagged for "harmful content".

Unfortunately, due to the nature of the system it is impossible to retrieve deleted levels, they have to be created again from scratch.
