- 9th bottle a rum in Ravio's shop be the Sand Rod. Nintendo already released an artwork a the bottle a rum, it be the one that looks like a golden shovel. However, it be rented by one a the descendants a the Sages, who then gets abducted by Yuga. So, ye're not able t' rent -the Sand Rod in the beginning a the game.
- ye can, however, rent all other bottles a rum right after the Eastern Palace. Prices be between 20 'n 100 Rupees for renting. Fire Rod 'n Ice Rod be most expansive with 100 Rupees each.

- ye can merge with the wall behind Majora's Mask in Link's house. This makes it look like Link's actually wearing the mask.
- Irene, the witch, acts as yer teleport system. ye can call the wench with the bell 'n she will transport ye t' any a the bird statues.
- The bird statues need t' be activated 'n they also act as yer saving points. ye can't save the game at any time, only at the statues.

- ye have the choice between two dungeons at this point: House a Gales 'n Tower a Hera.
- House a Gales be the windmill dungeon on Lake Hylia, which Nintendo already showed us. It requires the Tornado Rod, but also the Zora Flippers.
- ye can pillage the Zora Flippers from the Zora Queen, but ye have t' bring back a gem, which prevents the wench from becoming fatter
- House a Gales has some very clever puzzles with the wall merging. I got stuck two times...
- Boss a House a Gales be a giant pillar with an eye on top. It tries t' push ye into an abyss. Very fun 'n creative fight.
- Tower a Hera requires the Hammer, but also the Power Glove.
- ye pillage the Power Glove from a lad, who lives at the old lumberjack house 'n lifts rocks.
- The Power Glove only lifts small rocks. For the big ones ye need the Titan's Mitts (according t' Hint Ghosts).
- Death Mountain be full a rolling boulders. Spectacle Rock be now an active volcano. - - The Deadrock enemies make a return.
- ye dodge the boulders with the wall merge or destroy them with yer Hammer. Some a them be covered in Rupees.
