There are other side quests that I either didn't complete or haphazardly bothered with. I located the Casino and did that "left-or-right" guessing game thing 100 silly times so I could get that stupid Star Egg thing, which I kind of needed to take out that Final Fantasy style optional boss in Monster Town, which, while difficult in the context of this game, is still significantly easier than Shinryuu and Omega Weapon in Final Fantasy V (although I can't remember how I even tried to beat either of those, since that was approximately 23 years ago that I played that game) or Ruby and Emerald Weapon in FF7. Watching those dumb stars dance over and over had me pining for the ridiculously overlong call magic animations from FF7.
I don't know if I ever won that dumb Yoshi race thing on
Yoshi's Island pardon me, Yo'ster Isle. Looking at the results, I guess I shouldn't care.
I didn't do that dumb beetle collecting thing on that hill you race up, nor was I ever able to catch the Princess the first time you do it. Did I miss anything?
I went through that waterfall thing a few times, but only managed a couple of Frog Coins. Which, by the way, aren't terribly useful.
Hope there was no big trick to that. The subsequent mini-game where you race a barrel down the river is annoying as f***ing hell, probably the dumbest thing in the game.
Mario working as a bellhop in that silly wedding hotel? The f***?
There are plenty of things that it seems like they rushed, or didn't have time to complete. Star Hill?!? Were there even enemies there? Did I hallucinate that star piece just sitting there and you just walk up and get it? Again, if only this game had more time in the oven. They probably had to get it out fast before the N64 showed up. Which is hilarious, because, y'know...N64, the console that had game magazines proclaiming Nintendo would be over with by 2000 if they didn't do X Y and Z right away.
Then there are the things in the game that are just buttholishly difficult, hilariously at odds with the patience the game's kid-friendly audience would probably have time for, or the general easiness of the game. Not just the 100 jumps thing, but also the hilarious fact that you won't find all the hidden treasure chests if you miss the hidden one that you can only get the first time you enter Mushroom Kingdom's palace, which the vast majority of gamers almost certainly would not find.
A favorite moment in the game is when 1985 8 bit Mario turns up in Booster's Tower, or just hearing that world map music again as if for the first time. I'd forgotten it. I like both the cutesy music in the game as well as the dark music, like the Kero Sewers or Vista Hill. It's creepy!!
The best SNES game I haven't played is probably Secret Of Mana. Play that and replay EarthBound and you can bury me.
