Wumbotize has the n°5 run in the Sprint category (37.66), and Squirtle has the n°10 run from a year earlier, with a mod note mentioning it's Wumbo on PC and a replay from the same channel.

Is this allowed? Was this just not noticed when he changed account?

Note that this was on controller (converted to keyboard input), but there was no controller option when submitting a run
