On the way to Oreburgh, Ash and his friends see Nurse Joy trying to help an injured Nuzleaf. Nuzleaf is too upset to accept her help, so Brock steps in to calm Nuzleaf down. With help from Bonsly, who Nuzleaf seems to think is a Grass-type Pokemon, Brock wins Nuzleaf's trust and treats its injuries. This Nuzleaf must be lost, since an old tree on the other side of the mountain is the only place in the area where Seedot, Nuzleaf and Shiftry are found. Ash and his friends volunteer to get Nuzleaf back where it belongs.
Team Rocket spies on the scene and decides Nuzleaf would be a great prize for the Boss. They show up with Meowth dressed as a Shiftry, hoping to trick Nuzleaf into coming with them. Their ploy is foiled, so they grab Bonsly and Nuzleaf. Brock tries to stop them and ends up getting carried away by Team Rocket too! That's no problem for Brock--Team Rocket lowers their guard after he cooks them a delicious meal, and Brock escapes with Nuzleaf and Bonsly. During the break-out, Bonsly even evolves into Sudowoodo!
Next Brock has to cross a river, but Sudowoodo dislikes water, so Brock puts it in its Pokeball. The problem is that without Sudowoodo, Nuzleaf gets upset! Brock has no choice, but to bring out Sudowoodo and encourage it to be brave. Then Team Rocket catches up with Brock. Croagunk does its best, but it can't hold them off forever, so Sudowoodo pitches in to help fight. When Ash and Dawn arrive on the scene, Brock even tells them he and Sudowoodo can handle Team Rocket themselves! A real Shiftry shows up looking for Nuzleaf, and once Team Rocket is sent packing, our heroes can rest easy knowing that Nuzleaf will soon be back home.
The episode's title may be a reference to the television show Leave it to Beaver.
This is also one of the few times the Japanese title was translated directly, or almost directly.
Everyone shouts out the title card.
Music from Lucario and the Mystery of Mew and Jirachi: Wish Maker is used as background music.
Professor Oak's lecture: Ash's Aipom
Pokémon senryū: エイパムが しっぽでつかむ サトシのハート Eipamu ga, shippo de tsukamu, Satoshi no hāto "Eipam, it seizes with its tail, Satoshi's heart."
A teaser for the tenth movie was broadcast after the Japanese premiere of the episode as part of the special broadcast.
The Japanese ending credited both A Staravia Is Born! and Leave It To Brocko!.
While the episode aired as part of an hour-long special, the credits were as they would have been had the episodes aired separately. As such, Staravia was featured but Sudowoodo was not.
This is one of the few episodes of the Diamond & Pearl series where Dawn's Piplup does not appear.
Ash and Roark narrate the next episode preview, which is one minute long instead of the usual thirty seconds.
When Team Rocket is eating the food Brock fixed for them, James comments that the food is as good as Nanny and Pop-Pop's.
This episode features a scene similar to Do I Hear a Ralts?, in which Meowth dresses up as another Pokémon (in this case, a Shiftry) but is exposed when he is scanned by a Pokédex.
In the scene where Team Rocket is eating the food Brock made, when Wobbuffet eats the food from its fork, as soon as it eats it, another piece of food appears on its fork instantly, without Wobbuffet moving at all.
When Meowth is lying to Shiftry about who attacked Nuzleaf; he says that Shiftry is the one who harmed Nuzleaf.
When Brock gave Nuzleaf the Oran Berries in a bowl, there were about 10-15 in the first shot, but in the shot after that, the Oran berries shrunk and multiplied.
When this episode aired in Japan, along with A Staravia Is Born!, there was no opening, and a cold opening intro. It went straight to the episode after the previous episode finished. In the English version, a cold open intro, possibly made up by Pokémon USA, shows Team Rocket starving, and Brock tied in a tree offers them some food.
When Dawn sees Nuzleaf, she asks, "Who's that Pokémon?", an obvious reference.
