Our heroes are on the path to Celestic Town, but the road runs through a narrow pass that's blocked by three irritable Psyduck. If Ash and his friends take a detour, they'll miss the Celestic Town Contest, but the Psyduck's Psychic-type attacks repel anyone who tries to get through. Ash and his friends do their best to force the Psyduck out of the way, but none of their Pokemon can get in an effective attack. The Psyduck aren't interested in negotiating with Piplup, either! Team Rocket pops in to try and recruit the Psyduck for Team Rocket, but they too are blasted out of the way.
There must be a reason for the Psyduck's behavior, so Ash hatches a risky ride on Gliscor and flies ahead to scout the path. While Ash is on his mission, Brock sings and dances to distract the Psyduck. Ash and Gliscor crash-land near a pond filled with more Psyduck, nursing their Eggs--that's way the Psyduck in the pass are on guard! Ash returns and reports to the others just before Team Rocket returns in an attempt to steal the Psyduck. Ash and his friends team up with the Psyduck to beat Team Rocket, earning some trust from the Psyduck.
A Psyduck messenger summons the Psyduck in the pass and everyone runs to the pond in time to see the Psyduck Eggs hatch. As Brock dishes up Pokemon food to help earn the Psyduck's trust, he wonders why the Psyduck are in a small pond instead of nearby Lake Psyduck. When our heroes investigate Lake Psyduck, they're attacked by Muk that have taken over the lake! Ash and his friends send the Muk flying into another pond, which just happens to be inhabited by female Muk. The Muk happily pair up and the Psyduck families return to Lake Psyduck, so the road ahead is clear for the trip to Celestic Town!
This episode is based on an event in the games. A group of Psyduck are initially blocking the route to Celestic Town but a potion provided by Cynthia cures their headaches and makes them move away.
Brock wears his outfit from Takeshi's Paradise in this episode, and music from that is used as well in the original Japanese version.
This episode marks the first and only time that Brock's Happiny got knocked out.
After it is knocked out, Dawn returns Piplup to its Poké Ball for the first time since Pruning a Passel of Pals!, in which the episode number is a reversal of this episode. Once it was returned, it didn't reappear for the rest of the episode.
Ambipom had not used Double Team since she was an Aipom, making this her first time since evolving. In addition, Ambipom hasn't used this move since The Keystone Pops!, 31 episodes earlier.
An earlier episode had a similar title to this episode. Both are references to the famous saying "the buck stops here".
When Dawn got her "Psyducklings" idea, Brock's hair is colored black instead of brown.
As Brock performs Takeshi's Paradise, the Takeshi's Paradise background music is removed.
