Warren James Cook, or better known simply as Warren Cook, is an infamous bad user from Go!Animate and YouTube, who has been subjected to more grounded videos than any other Go!Animate user. He only appears as a non-playable character in Story Mode: The Stretch Squad, alongside Memy9909.
Role in The Stretch Squad
Warren first appears in Road to Train Station, where it is revealed that he and Memy are members of The Stretch Squad, working under Matthew Whitehead. They managed to find a trophy of Sonny Slaven, but they tell Matthew that they were unable to find trophies of Lee Saunderson and Brad Till as well, which angers Matthew, who threatens to fire the duo, but decides not to. But he still tells them to find more trophies by the following day, or else they would be doomed.
