* The instructor says {{type|Electric}} moves do not work on {{t|Rock}} Pokémon, in reference to Pikachu's Thunderbolt failing to affect his {{p|Graveler}}. In reality, {{type|Electric}} moves don't work on {{t|Ground}} types, which Graveler is also, but have normal effectiveness on Rock types.

* In one scene where the gang talks to [[Nurse Joy]] and {{Todd}} takes pictures of Pokémon, there is a Trainer with a green-colored {{p|Weedle}}. Coincidentally, Weedle is green when {{Shiny}} in {{2v2|Gold|Silver}}, albeit a different shade.

* The computer's image of a {{p|Caterpie}} leaves a section of its body colored the purple on the screen.

* When Ash is returning Arbok to its Poké Ball, the number seven seen on his jacket has vanished.

* After Ash answers the tail flame question, and the view reverts to the big screen, the picture on the screen shows a flame from Ponyta's mane, not tail, but before Ash is answering, it shows the correct flame.
