Notes:

So twitch user http://www.twitch.tv/razorsharpfang had the bright idea to do a Twitch Plays of Undertale. Apparently that wasn't so insane as it sounds, as they eventually made it all the way to Asgore.

But they didn't expect the hardest boss in the game, the Windows XP Screensaver!

They obviously didn't call themselves Chara and weren't thorough enough to get to LV 19, but I couldn't check the actual values so I just pretended that Windows XP was their version of a Bad Time.
