Continuity mistake: At the beginning of the episode, Brock's black belt turns green. (00:01:15)
Revealing mistake: When Pikachu meets Puka on the cliff, we are treated to an aerial shot which shows the ocean below. There is sunlight reflecting off the surface, but as the camera moves, the lights pass in front of the two Pikachu on the cliff. (00:07:26)
Continuity mistake: When Brock says, "Looks like a greenhouse," he is holding the straps of his rucksack, but in the next shot, he is not. (00:04:08)
Continuity mistake: When Ash is walking to the torchbearer, the people in the background change. (00:03:32)

Continuity mistake: When Brock mentions that Ash has to win on the rock, grass, water, and ice fields to compete at the Indigo Stadium, a staff member of the Pokémon League is not smiling, but in the next shot, she is. (00:03:07)
Character mistake: When Team Rocket first sees Mandi doing his magic tricks, he produces a bunch of Pidgey. Meowth says "I like those Pidgeotto." He's dealt with Ash's Pidgeotto on numerous occasions, so there's no reason that he shouldn't be able to tell the difference. [This mistake only appears in the English version. In the Japanese version Meowth doesn't even mention Pidgey nor Pidgeotto at all.] (00:04:49)
Continuity mistake: When Professor Oak and Delia are first seen watching Ash's first battle at the Indigo Plateau Conference, Delia has a person to the left of her, and her hands are in her lap, but in the next shot, she does not have a person to the left of her, and her hands are clasped together. Also, she and Professor Oak are smiling, but in the next shot, they are not. (00:11:46)
Continuity mistake: When the Officer Jennys say that the news reporters are Team Rocket, Meowth's disguise disappears. (00:12:31)
Character mistake: When Mandi brings out Golbat, Brock says, "Kingler is really weak to air attacks." But Kingler's a Water type, which has no weakness to Flying-type attacks.
Suggested correction: Brock is saying that Kingler is vulnerable to attacks from the air, not that it is weak to Flying-type moves.
Revealing mistake: When Ash brings his first piece of meat into his mouth, another one disappears into thin air. (00:09:09)
The Fourth Round Rumble - S1-E77
Character mistake: When Officer Jenny orders her Growlithe to attack Team Rocket's balloon, she refers to Growlithe as Arcanine. [This mistake happens only in the English version. In the Japanese version she refers to Growlithe correctly.]. (00:12:21)
The Fourth Round Rumble - S1-E77
Character mistake: When a poster for the Pokémon League is seen, it misspells it as "Pokemon League." (00:20:22)

Factual error: When the lift starts working again, the cables on one side of the lift are being pulled downward while the ones on the other side remain in place. However, lifts are pulley systems; if one end is pulled down, the other end is pulled up. (00:05:24)
