Momomomo is one of the marbles on Team Momo. Momomomo is well known for his injury at the MarbleLympics, during the "Fidget spinner collision" event. The injury was caused when Momomomo was flung into Wispy from the Midnight Wisps by a fidget spinner and a chunk of his body was knocked clean off. This horrific injury was featured #1 in Jelle's YouTube video, "MarbleLympics 2017 Top 10 Video Highlights".
Momomomo was forced to sit out for the remainder of Marblelympics 2017 after sustaining a chip to the side. He watched the rest of the 2017 MarbleLympics from the stands as Mimo substituted in his place.
Despite rumours saying that he may not be able to compete in any MarbleLympics ever again, he has fully recovered from his injury and is back with Team Momo, competing for the 2018 Winter MarbleLympics.
However, MarbleLympics News stated that Momomomo wasn't 100%, as he didn't perform well in his qualification event. On the other hand, Mimo, who replaced Momomomo for the remainder of the 2017 MarbleLympics had won a qualification event which contributed to their appearance in the 2018 Winter MarbleLympics. Team Momo had revealed that Mimo had made the starter while Momomomo was demoted to reserve. Momomomo was part of the bobsleigh team in the event, but received concussion in it thus making his participation for the remainder of the 2018 MarbleLympics unknown. Momomomo competed in the qualifications for the 2019 MarbleLympics.
