The Tunnel (Japanese: トンネル Tunnel) is one of the six major areas of Pokémon Island. As its name suggests, it is a long dark tunnel that sits at the foot of an active Volcano. Much like the Beach, many man made structures exist outside and within the tunnel, including a decommissioned power plant that has begun to fall into disrepair.
With no human presence remaining on the island, the power plant is no longer in use; however, some auxiliary power still remains, keeping the automatic vault doors operational. Similar to many power plants and industrial complexes around the world, the tunnel has become home to at least eleven* different species of Pokémon, most of which are Electric-type Pokémon attracted to the power plant.
The power plant has one generator, which is a five-part conical shaped device that is partially submerged in a pool of water. Two pipes run from the generator into the water below, and another between the generator and turbine housing. It is likely that pumping water in and/or out is part of its design, either to generate the electricity or cool off its components. At the top of the conical portion is a dome, with an electrode protruding from it. If Zapdos is hatched from its egg, it will begin attacking the generator, thus bringing it and the power plant back online.
Towards the end of the course is a spotlight, with some rocks and discarded debris in front of it. If the power is turned back on, the spotlight with these objects will project a shadow onto the wall. This shadow looks remarkable like a Pinsir, and as such is named 'Pinsir Shadow' by Professor Oak. This is one of the six Pokémon signs spread across the island.
There used to be a Power Plant in this long, dark tunnel. I can't wait to check it out!
|Electrode||Found outside and inside the tunnel. Electrode do not respond to anything, unless they are standing still and are hit by an item, in which case they use Explosion. Causing the Electrode near the end of the tunnel to explode will open a new area of the island for the player to explore.||Electabuzz||Found multiple times before and within the tunnel. A Pester Ball will cause it to fall and temporarily block the ZERO-ONE's path.|
|Pikachu||Before entering the tunnel, a Pikachu appears; photographing it a few times will cause it to run to an Electrode and hop on top of it. This Pokémon also is found near an enormous Egg within the tunnel. Leading it to the egg with Pokémon food followed by a Thunder Wave-inducing Poké Flute melody causes the Pikachu to attack the egg, hatching it. A third Pikachu appears near the second Haunter, playing with a Diglett.||Kakuna||A group of Kakuna dangle from the opening of the tunnel. They drop down whenever Electrode explode.|
|Zapdos||The giant egg, when hatched by Pikachu's Thunderbolt attack, releases Zapdos. It will fly to a generator and begin attacking it, bringing the rest of the power plant to life.||Magikarp||After passing by Zapdos's egg, a small pond within the tunnel is home to Magikarp. Tossing an item into the deep pond can entice a Magikarp to leap from the water.|
|Zubat||Midway through the tunnel, there are two metal doors that divide the tunnel into thirds. Each time one of these doors opens to let the ZERO-ONE pass, a Zubat flies through.||Haunter||Just past where Zapdos hatches, an odd purple sphere is moving around. Another one can be found near where Pikachu and Diglett play. If photographed, the developed photos will reveal the orbs to be Haunter.|
|Diglett||Near the end of the tunnel, a Pikachu is found playing with Diglett.||Dugtrio||Taking a photo of Diglett will send Pikachu off to play with another. Photographing the next Diglett the Pikachu finds repeats the process, until the Pikachu comes across a Dugtrio. Take another picture to make another Dugtrio appear, and again for three Dugtrio to raise out of the ground.|
|Magnemite||At the tunnel's end are a trio of Magnemite. Each Magnemite emits a Supersonic which distorts the photo, but distracting them with Pokémon food causes these Pokémon to lower their guard.||Magneton||Luring all three Magnemite near one another with Pokémon food causes them to fuse into a Magneton. It no longer uses Supersonic after evolving.|
