So, while playing PMU it is quite apparent the the held item Light Ball was only available as a Holiday Cave exclusive item. If there is any way to add this item to another location, lets say Sandy Shallows with the Secret Room Pikachu as a 0.01% or even 0.001% drop rate, or have it in Tanren Chambers Electric Exit End Boxes at either F84 or F99, then it would be more accessible to more players. With how Light Ball is most likely this Idea would be rejected in some way as the stats increase by x2 for Attack and Special Attack, but having it at a more difficult/late game location would balance it out in some manner.
I am hoping this gets pushed through as it would be a nice item for Pikachu Mains to have if they want to play the game without evolving their Pokemon.
