How do I get the last star? 🕵️‍♂️✨

Anyone know how to get the neon stick thing for crafts?

https://drive.google.com/file/d/1bVjN9Z9Bq1-Fge7msvhHUFJ-tbNfBGVM/view?usp=sharing I don't know what triggers the problem--the point of the game is not really knowing what does what, and discovering things. But it seems to be related to moving the ground? Seems like it's triggering multiple guitar stems over and over all playing on top of one another. And when I put the ground back to relatively flat it stops. Even when it's doing it's insane guitar thing, and I turn off the music it keeps playing--again...

How do you get lightning? I'm on the last map.
