You have to read the dialogue... too much stuff to name. Like how the Snifits want to throw the living cake into Booster's mouth and do and are just like "yep; wedding was a success" while Mario walks out with Peach on his arm, and of course the (in)famous scene of Booster kissing Bowser.
Like Booster and the Snifits are the enemy but there's that weird Looney Tunes dynamic where they act stupid and allow you to help them; definitely worth a replay, not to mention I went into the cake battle without Mallow or healing items so I had to abuse the SNES Classic save state feature to luckily beat it, because the last time I saved was before Knife/Grate Guy (Nintendo was on some kind of creative high when they made this).
This game doesn't get enough love: perfect amount of humor, seriousness, super creative characters, the combat is just deep enough and the pseudo 3D is super charming and hasn't aged a bit; such a far cry from what Nintendo is producing these days.
'96 was unbelievable, with the release of this and then Mario 64 shortly after... totally comparable to Rabbids followed by Odyssey last year; I don't care what anyone says, but Mario/Rabbids feels like SMRPG to me, between the humor and all the other stuff I listed.
