Half of Kurt’s poké-balls in Gen 2 are glitched in hilarious ways. The Fast Ball only works on the slowest 3 pokémon that can run away (Tangela, Grimer and Magnemite, as opposed to the ones that always run away, the 3 legendogs), the Moon Ball only works on pokémon that evolve via BURN HEAL, and best of all, the Love Ball only works on pokémon that are the same species and gender as your active one. It’s actually a gay ball. <3
so yes, every single time you used those poké-balls back in the day was actually a placebo. Go figure. But obscured stats and calculation are the norm in Pokémon, so it’s no wonder no one, well, “caught” this glitch.
(I recommend checking TheZZAZZ and ChickasaurusGL on youtube for more pokémon glitches. There’s… a lot. There’s always more. And they don’t stop.)
