Questions about Freaky Fusion Frankie Recharge Chamber Mechanics!

Hi ghouls,

I just got my very own Freaky Fushion Frankie Recharge Chamber play set, and was wondering exactly what the controls are for it? I know it seems simple, press down to statically charge her, but I’ve noticed that sometimes when I just push the button it changes the lights and then turns off? But sometimes that doesn’t happen. Could anyone here with the doll explain how it works a little better 😭 ? Or if any of you guys still have/remember the manual and could share?

Thank you!
