Moreover, if Link forgets to collect the Heart Container dropped by the Helmaroc King, he can still retrieve it in the exact same place where his sword was dropped after being launched in.

*** Played straight prior to Chapter 5 with [[WombLevel the belly of a whale Mario and his team must go inside of]] in order to relieve him of a bellyache.

The Chapter 6-7 intermission is her [[PointOfNoReturn last chance of leaving Mario those items that she finds]], because afterwards, she can't enter the passageway again due to her last segment after all the Spirits are freed being a cutscene prepping for the [[FinalBoss final fight]].

*** This game segments after every Chapter where you get to play as Peach and Bowser. While these mostly boil down to uncovering information and minigames, the Bowser segments that come after Chapters 2, 4 and 6 contain unique side-scrolling levels based on ''VideoGame/SuperMarioBros1''. As these "Bowser" levels containing nothing of any real significance, once you complete one, there is no way of replaying it. This also applies to Bowser's Castle right after Hooktail has been defeated.

Moreover, if Link forgets to collect the Heart Container dropped by the Helmaroc King, he can still retrieve it in the exact same place where his sword was dropped after being launced in.

*** Subverted with the Forsaken Fortress, which sits completely abandoned after Link [[ItsPersonal rescues Aryll]] and [[BestBossEver defeats the]] [[FeatheredFiend Helmaroc King]], save for a few Keese and Rats. Link can still revisit the fortress, especially through the portal activated in [[TheVeryDefinitelyFinalDungeon Ganon's Tower]], but the Helmaroc King's (consisting of the prison where Aryll was locked up along with Maggie and Mila and the top of the tower) and Ganon's chambers (the old pirate ship, also at the top of the tower) cannot be accessed again due to the old ship being burned up by Valoo just after Link and Tetra [[spoiler:later revealed to be Princess Zelda]] escape with Komali and Quill. Moreover, if Link forgets to collect the Heart Container dropped by the Helmaroc King, he can still retrieve it in the exact same place where [[NoGearLevel his sword was dropped]] [[StealthBasedMission during the first visit]].

*** Also played straight with the tomb of Madam Merlar after Mario and his team obtain the Star Stone from her, which is needed to access the summit of [[SlippeySlideyIceWorld Shiver Mountain and the Crystal Palace]]. Placing the stone in the pedestal causes a flight of staircases to rise, blocking the entrance of the tomb.

Lavalava]][[note]]due to the eruption after completing the dungeon, the bottom floor leading to the lair becomes unsuitable for Mario and his team to walk on[[/note]] and the [[SecretPath secret passageway]] in [[GildedCage Princess Peach's bedroom]][[note]]Peach, whose castle is [[AllYourBaseAreBelongToUs sitting on top of]] [[TheVeryDefinitelyFinalDungeon Bowser's Castle]] after it was hoisted by the latter castle into the stratosphere, cannot enter the passageway again after Chapter 6, since Mario and his team rescued the penultimate Star Spirit, and Mario and his team also cannot access it upon reaching the castle for the [[FinalBoss final fight]] against Bowser[[/note]].
