ゼルダの伝説：神々のトライフォース
The Legend of Zelda: Triforce of the Gods

For whatever reason, the Bomb Shop found in the Dark World where Link's House is in the Light World now has an oversized pink bomb available for a mere 100 rupees. Link buys it, of course.

The jumbo bomb follows Link around, but stops moving and starts counting down with a press of the A button, or after certain sudden moves (such as jumping).

Remembering that sealed doorway back at the pyramid, Link tries setting the bomb off there... and it blasts open a hole large enough for Link to enter. Inside is another mysterious fountain, like the one behind the waterfall in the Light World, and just like at the other one, Link can try throwing various items in. So he tries his sword. A grotesquely fat creature barely recognizable as a faerie appears, asks the usual question, gives the usual speech, and upgrades Link's sword.

The sword now glows gold, and its damage is again (usually) doubled.

Link tries tossing in his bow next. The faerie appears and asks the usual question, but doesn't give the usual speech.

All of Link's current and future arrows are now silver. Not only are they silver and shiny, but they also hurt much more than before... so much so that they'll kill any normal enemy in a single hit, even those that took five normal arrows.

The familiar warp point on the mountain is in the wrong place to reach Turtle Rock, but between the Magical Hammer and Powerful Gloves, Link can reach the top of a rock in the Light World that corresponds to Turtle Rock in the Dark World. Three pegs stick out of the top, and hitting them in the correct order makes a warp tile appear on the rock. Link steps on the tile and appears on top of Turtle Rock, a massive boulder shaped like a turtle that has no apparent entrance. However, there's a platform above the head, with a symbol that looks a lot like a medal engraved with a wavy pattern. Link tries standing there and using the Shake Magic. Sure enough, the shockwaves make the head collapse, revealing the entrance.

Just inside the entrance, Link finds another telepathic tile.

Again, "old man" speak implies Sahasrahla.

The dungeon is full of massive pits. To cross them, Link needs to use the Staff of Somaria on question marked spots at the end of dotted lines over the pits. This makes a platform appear that will travel along the dotted lines. Other than that, and some eyes in the walls that shoot lasers at Link, Turtle Rock is fairly routine.

Riding some pipes over hot lava gets Link the big key, and before long he finds the big chest...

The Mirror Shield is a golden tower shield that doesn't, unfortunately, reflect attacks, but it does block nearly any ranged attack, including large fireballs and laser beams. And that comes in handy with all the laser eyes in the walls.

After considerable journey deep underground, Link finally reaches the boss room. It's a three-headed stone turtle. The center and largest head occasionally lunges at Link, but doesn't do anything else and is invulnerable. As for the other heads... one is bright blue and breathes ice, while the other is bright red and breathes fire. Both are invulnerable until hit with the opposite element, which stuns them long enough for Link to get in several solid sword blows. Once both side heads die, the turtle pulls into its shell and explodes... but it's not done yet. The inner part, resembling a large stone snake, bursts out and chases after Link. Fortunately, it's a bit sluggish and has a poor turning radius. The middle is vulnerable, and a few hits takes it down, this time for real. After a satisfying explosion, the final heart container appears, giving Link twenty if he's collected all the heart container pieces. The crystal imprisoning Princess Zelda drops.
