Quoted from Tdavis7965:
Has anyone replaced this 04 piece yet? Found this up in the wonkavision stopping the multiball from coming down lol.... any other mods besides stock replacement?
I got this mod for Xmas and really enjoy it. https://pinballmods.co/willy-wonka-pinball-jjp/wonkavision-stage-captive-ball-protector
It protects the Oompa Loompa as well as keeps balls from getting trapped above the captive ball (i.e. does what "piece no. 4" did.)
