Ash, Misty, and Brock make their way through Gringy City. The air and water
here is incredibly polluted thanks to the many factories. Ash notices that
Pikachu is acting weird. Sparks are coming out of its cheeks and its face is
red. A shadowy Pokémon watches from a nearby alley.
Ash wears rubber gloves as he rushes Pikachu to the Pokémon Center. Meowth
watches them enter from a periscope deep in the sewers. Jessie and James
begin to do the motto, then complain about the horrible smell instead. Meowth
gives them scuba suits to wear, which pumps oxygen and air freshener. Meowth
tells them to dive into the water and swim through the pipes to the Pokémon
center, but Jessie and James refuse. Meowth pushes a button which delivers
the hapless humans an electric shock. They reluctantly enter the sludge water
of the sewers.
Ash rings the bell at the desk. Nurse Joy comes out of a nearby room,
yawning. It's late at night and she dismisses Pikachu's condition as a cold.
When Ash yells at her for not being very helpful, she explains that the
sparks coming out of Pikachu's cheeks are an early symptom of a cold in
electric rodent Pokémon. She suggests that they leave Pikachu there for the
night, and it will be fine in the morning.
At the same time, a large group of Grimer block the water flow into the
hydroelectric power plant, causing the power to go out. This causes the power
supply to Team Rocket's scuba equipment to go dead. There are also several
Pokémon in the intensive care unit at the Center, and if the power is not
restored soon, bad things will happen! Ash, Misty, and Brock decide to head
for the power plant to try to do something. Pikachu cries out as they leave.
They ask Officer Jenny for directions, as Pikachu comes out of the nearby
Misty realizes that Pikachu is afraid that they won't come back for it later,
so Ash decides to let it come along. Pikachu jumps into Ash's arms and Ash
gets shocked as the shadowy Pokémon watches from a nearby bush.
Somehow, Meowth gets Jessie and James back on the surface level as they gasp
for air. Meowth watches as Ash, Misty, and Brock race past the alley they are
The group arrives at the power plant. They enter and nobody is there to greet
them. Misty looks at a map and points out the direction to the central
control room. Misty gets spooked as something flies behind her. After a
philosophical discussion about Misty's cowardice, both Misty and Brock spot
something behind Ash. He turns around and nobody is there. The shadowy figure
appears behind Pikachu. Ash looks it up on the Pokédex and it's a Magnemite,
the magnet Pokémon. Ash decides to try to catch it, but Magnemite only seems
interested in Pikachu. Magnemite seems to be in love with Pikachu for some
Ash yells at the Magnemite to cut it out, and the Magnemite backs off. A
nasty stench enters the corridor. They turn around to see a grating fall off
the ceiling, followed by several Grimer. Brock decides that it would be best
not to say anything to insult their pride. Ash pretents to compliment their
unique smell, but Misty says it stinks, and a Muk rises from behind the
Grimer. With a command from Muk, the Grimer attack. Ash, Misty, Brock, and
Pikachu run. As they round the corner, they run into two plant workers. The
Grimer approach, and they all start running for the control room. They all
hide in the control room. One of the workers explains that the Grimer are
clogging the sea intake, preventing the power from coming back on.
The Grimer bust down the door. Pikachu uses its thundershock attack to knock
out some of the Grimer, but it's not good enough. Suddenly, the Magnemite
knocks out the grating above them, and several Magnemite and Magneton arrive.
Their combined electric attack is enough to chase away all the Grimer. They
also manage to get rid of the Grimer blocking the flow of water into the
power plant, and the power is restored.
However, one Muk remains. Pikachu uses Thundershock, and Pikachu's stalker
Magnemite assists with a thundershock of its own. The combined thunder attack
knocks the Muk unconsious, and Ash captures it in a Pokéball. To his
discontent, he realizes that the smell of the Muk comes THROUGH the Pokéball!
Everyone is now outside, and the sun is back up. Pikachu seems to be a lot
better now. One of the power plant workers explains that when an electric
mouse builds up too much electricity, its body becomes magnetized and it
seems as though it has a cold. The Magnemite is no longer interested in
Pikachu. Magnemite was in love with Pikachu because it was magnetized, but
Magnemite has no interest in a non-magnetized electric mouse.
A Gyarados submarine comes out of the water with a large magnet attached to
it. Team Rocket's plan is to use the magnet to capture Pikachu due to the
fact that its body is now magnetized. What they DON'T know is that Pikachu is
no longer magnetized. When they activate the magnet, Magnemite and Magneton
from all over town are sucked onto the magnet. The weight of all the
Magnemite and Magneton cause the sub to sink.
Meanwhile, at Professor Oak's house, a Pokéball arrives from Ash. The
Pokéball opens up, and Professor Oak covers his nose in disgust.
"What's the idea of sending me a Muk?! YUCK!"
