Momo YouMookSaidTimon (now known on her new account as ShimmeringNight) is a famous GoAnimate user.
ShimmeringNight is best known for making GoAnimate videos with GoAnimate versions of cartoon and anime characters. She also has done things other than grounding videos using GoAnimate, such as gameplay of a fictitious video game called Magical Girl Adventures, a short film called The Story of the Pop Star Dolls, channel bumpers, a reading of a Spinpasta story written by Momo YouMookSaidTimon, and the short lived Ask Momo YouMookSaidTimon. The first GoAnimate grounded video Momo YouMookSaidTimon uploaded on her former account was Anthone is Grounded For Life!, and the last GoAnimate grounded video uploaded on her former account was "KimiTheAnimationGuy1 gets Grounded on Christmas".
In late June 2014, after a five hiatus due to real life conflicts, mainly school, Momo YouMookSaidTimon started using her sub account, DarkestNight, which is also used to make YouTube Poops and AMVs, to make new GoAnimate videos. Her latest grounding series is Darby Gets Grounded, focusing on Darby from My Friends Tigger and Pooh, but she cancelled the Darby gets grounded series later on because another user didn't like the videos out of Darby.
