* {{Balloon Belly}}: Petey Piranha. You defeat hir by [[{{SuperMarioSunshine}} inflating hir with water, then stomping on hir exposed belly button.]]
* {{Call Back}}: Only Hoo and Blizzaurus are original bosses, and Petey Piranha or "[[{{MeaningfulTitles}} Boss]] [[{{AtrociousAlias}} P.]] [[{{SameFaceDifferentName}} Plant]]" and Gooper Blooper are defeated in similar ways to their appearances in SuperMarioSunshine.
* GameBreaker: Practically every upgrade is one of these. Each one makes it more and more difficult to die.
* ItsEasySoItSucks: Compared to other ''Mario'' games, ''SPP'' is rather easy to finish... right up until you get to [[ThatOneBoss Bowser]].
* ThatOneBoss: Bowser. Has hard-to-dodge attacks and [[GuideDangIt it's hard to figure out how to beat him]]. Luckily, you're healed between his two phases.
* TheyWastedAPerfectlyGoodPlot: Many say that this would be a good idea if it weren't for the low difficulty and the Vibes.
