Undertale the musical

There are 2 UNDERTALE the musicals
The one by Man on the Internet, giving lyrics on the Undertale ost, and all the songs together are a whopping 4 hours and is amazingly high quality

And the one by LHGUENY, that has terrifyingly bad animation, and annoying lyrics
Undertale the musical can also refer to the UNDERTALE Genocide package by Man on the internet, and is basically Man on the internet's Undertale the musical, but for the Genocide route, not the Neutral and Pacifist route

John: did you see Undertale the musical?
Gary: which one, the good one or the bad one?
