Custom Enemy/Powerup mushroomeat Sound

[Minimun3Dashers]

I am trying to make a invincible character with a powerup that keeps transforming into the same enemy every 0.2 seconds but what stresses me out is the eternal mushroomeat sound, How do i turn it off to only that enemy without animations?

something like, "growsound": false does not work, so what do i do?

You can't turn off the powerup sound
