-The episode starts with Hikari running ahead of Satoshi and Takeshi to get the newest Poketch model. However, at this time, no one knows what the new model is.
-The gang arrives at the Pokemon Center, but they're told they're at the wrong one! The Pokemon Center they need to go to is on the other side of the mountain!
-As Joi tells them where the Pokemon Center is, Takeshi starts to flirt with Joi. Gureggru appears and uses Poison Jab, but Takeshi actually dodges it! The scene ends with Satoshi and Hikari carrying Takeshi off while Gureggru just sort of stands there.
-The gang starts running along a mountainous path when they're approached by Musashi-tachi in disguise. The three tell them that they're the 100th visitor (or something like that) to the area, so they invite them into a detour that will get them to the Pokemon Center faster. Kojirou also gives a map to Hikari to use.
-Before letting Hikari and the others continue into the cave, however, Musashi-tachi ask everyone to release their pokemon so they can all take a big group picture. Unknown to our heroes, the Rocket trio has a net hanging above them, waiting to be dropped.
-Suddenly, the cave starts to rumble, and a group of Golone and Golonya roll past our heroes! After the dust clears, our heroes are nowhere to be found! Kojirou wonders what they'll do now, but Musashi says that they'll be easier to catch now that they're separated.
-Next, we see Hikari walking through the cave by herself, holding Kojirou's map. As she looks around, scared, she sees a pair of glowing eyes that look a lot like Gureggru's...
-Elsewhere, Satoshi is seen with a number of tunnels in front of him. The trainer stops for a minute before choosing the one on the left. The tunnel leads outside, where he sees a giant labyrinth. On top of one of the stone walls is Satoshi's rival, Shinji! The trainer from Tobari City is busy trying to capture an Onidrill, but when Satoshi calls out to him to ask if he's seen the others, the pokemon escapes! An angry Shinji tells Satoshi that he doesn't have time for him and walks off. As Satoshi is left standing there, he has a humorous vision of Hikari having Iwaku use a Wrap attack on her. The trainer decides to continue through the maze so he can reunite with his friends.
-As Satoshi continues through the maze, Musashi, Kojirou, and Nyasu wait for him, disguised as boulders. The Rocket trio position themselves on a cross-shaped path in a way that forces Satoshi to go forward. Once Satoshi passes by, Kojirou moves so that the next person who comes by is forced to turn left. Pikachu arrives at the intersection and turns left, separating itself from Satoshi even more than it already was.
-Musashi and Kojirou, undetected by Pikachu, are about to chase after the mouse pokemon when the herd of Golone and Goronya roll past. After they go by, an Iwaku charges through and hits the trio, causing the Rocket-Dan to be sent blasting off.
-Back at the exit to the cave, Hikari and Gureggru emerge. Hikari spots Shinji, who's still trying to capture Onidrill. She asks him if he's seen Satoshi and Takeshi but gets yelled at for distracting him. Hikari takes a path into the labyrinth and Shinji resumes his capture. However, at that moment, Takeshi, along with Mukubird, Aipom, and Naetle, all appear and ask him if he's seen his friend! An upset Shinji wonders why everyone keeps interrupting him...
-After Shinji storms off, Takeshi asks Mukubird to fly over the labyrinth to see if it can spot his friends.
-Elsewhere, Pikachu comes across Mimirol and Pipinku, who are arguing amongst themselves. After breaking up the fight, Pikachu carries Pipinku on its back and grabs ahold of Mimirol's hand to get it to come with them. However, when it does this, Mimirol starts to blush.
-Meanwhile, Hikari and Gureggru press on through the maze. Suddenly, the Iwaku that attacked the Rocket-Dan comes rampaging straight for Hikari! Gureggru, thinking quickly, uses its Poison Jab to create a crack in the wall and then pushes Hikari into it at the last second. Iwaku pases them by as Hikari, dazed by what just happened, thanks Gureggru for saving her.
-We then see a scene with Pikachu, Mimirol, and Pipinku, all getting along.
-Next, we see Satoshi arrive at a dead end. He swears, however, that he'll reunite with his friends if it's the last thing he does!
-----Commercial Break-----
-Satoshi continues to press forward. He comes across Potchama, Buoysel, Usokki, and Pachirisu. Potchama and Buoysel are arguing, Usokki is nervously stamping its feet, and Pachirisu starts to tear up. Satoshi runs up to the pokemon to stop the fighting, but an emotional Pachirisu accidentally shocks everyone!
-Suddenly, the Iwaku from before makes its way toward Satoshi! The young trainer orders Potchama to use Bubble attack while he orders Buoysel to use Water Gun. After defeating the rock snake pokemon, the two water-type pokemon high-five each other.
-Above, Mukubird continues to search for its comrades. Hikari spots the bird pokemon from the ground and starts to chase after it. The pokemon returns to Takeshi's side to report that it couldn't find anyone.
-Takeshi presses onward. Before long, he comes across a pyramid-shaped stone structure, at the top of which is a tree and green grass. Under the tree are Pikachu, Mimirol and Pipinku! Takeshi's pokemon gives Pikachu some flowers, and the electric pokemon responds by smiling awkwardly.
-Takeshi waves to the pokemon to make his presence known. At that time, Hikari and Gureggru arrive and reunite with Takeshi as well! Hikari wonders where Satoshi is, and Takeshi responds by asking Mukubird to search for its trainer again.
-Suddenly, the Rocket-Dan's pink mecha hand shoots through the air and grabs Mukubird! After performing their motto, the Rocket-Dan place Satoshi's pokemon into a cage. They then attempt to capture Pikachu with their mechanical hand, but the pokemon escapes. So, instead of pursuing it, the Rocket-Dan simply retreat with Satoshi's Mukubird.
-Hikari and the others chase after the Rocket-Dan's Nyasu balloon. As they run, Hikari calls out for Satoshi. The young trainer hears his traveling companion and yells out to her. Before long, our heroes discover that Satoshi is on the opposite side of a huge wall that they are unable to get around.
-Satoshi is about to turn back to try another path, but the Rocket-Dan use their pink mechanical fists to pummel the walls around him, creating a bunch of rubble that traps Satoshi at the dead end.
-Satoshi responds by ordering Potchama to use Bubble Beam, Buoysel to use Sonic Boom, Usokki to use Mimic, and Pachirisu to use some electric attack on the Rocket-Dan. However, Pachirisu's attack goes awry and electrocutes Satoshi-tachi, allowing the Rocket-Dan to escape.
-Once the Nyasu balloon is out of sight, Takeshi yells at Satoshi (from the other side of the wall) to have his pokemon attack the same spot that they're going to attack in an attempt to break the wall. Takeshi then picks up a rock and hits the wall with it...Satoshi listens to the sound the rock makes and knows exactly where to hit the wall.
-Now that both sides know what part of the wall to hit, they order their pokemon to attack. Takeshi asks Aipom to use Swift and Naetle to use Razor Leaf. Satoshi asks Mimirol to use Ice Beam, Potchama to use Bubble, Buoysel to use Water Gun, and Pachirisu...to sit this one out. Hikari asks Gureggru to use Poison Jab.
-As the pokemon attack, Pipinku walks by with a rock about twice its size and throws it at the wall. Our heroes admire Pipinku for trying to contribute to the team.
-After a long while, the attacks break through the wall, enabling everyone to reunite. Just as this happens, the Rocket-Dan reappear and start to descend toward our heroes. But wait! Pikachu, who had been missing during the big melee attack, reveals itself on top of the giant pyramid! The electric pokemon, taking advantage of its altitude, jumps up to the Rocket-Dan's balloon and uses Iron Tail to free Mukubird from its cage. It lands on the bird pokemon who then swoops in on the Nyasu balloon so Pikachu can get close enough to Thunderbolt them. The Rocket-Dan are sent flying into the sky.
-Later that day, Hikari arrives at the correct Pokemon Center. There, she gets a new Poketch application; Coin Toss! As Hikari admires her new update, Takeshi starts to hit on Joi. Gureggru steps in with a Poison Jab and, unlike last time, succeeds in stunning its trainer!
-As our heroes continue on their journey to Yosuga Town, they come across a fork in the road. Satoshi asks Hikari to use her new Coin Toss application to decide which way to go. Hikari announces that if it comes up heads, they'll go left; if it comes up tails, they'll go right. As the Coin Toss tells our heroes to go right, Takeshi wonders if trusting the Poketch for something like this is a good idea...
