It's kind of funny to me to hear people say that the item spawn rate it too high. Y'all clearly didn't play with items set to very high like I did. To me, the spawn rate feels just about right - I'd even like to see a few more items, to be honest.
These are the only two I'll really miss. Gulpin was great because you could rack up a ton of damage on someone who got swallowed. As Luigi I could regularly hit 2-3 Super Jump Punches on a trapped opponent. As for Bonsly...man, what an adorably deadly projectile. I got so many kills with that little guy. Too bad he got replaced by Villager's down special lol.
As for Munchlax, good riddance. All he ever did was eat the good items and mess up my plans. He was the Nintendog of Pokeballs.
