It turns out that Super Mario Odyssey is almost as fantastic when it’s broken as when it works. Players are digging up all kinds of glitches and sharing the results online for the rest of us to enjoy ... and maybe even recreate.

The most popular one by far is this quirk shared user NichtSascha on Twitter. Ever wanted to just play as Cappy? This glitch let them do just that in co-op mode, where one player accidentally killed off Mario while Cappy was able to live on.
