A Differently Colored Yorunozuku! Catch It!! - S3-E38
Other mistake: When the Pokédex tells facts on Noctowl, Ash's right ring finger and the one above lack a separating line, making it appear as if they are fused together. Also, the angle created by the screen and the identifier is a 130° angle, but in the next shot, it is a 170° angle. Additionally, Ash's right index finger is at the top of the section with the screen, but in the next shot, it is more in the centre. (00:02:08)
Answer: There are a lot of fan theories around this, but the most common theme is that Pikachu had another trainer before Prof. Oak, who gave him to Ash. Pikachu didn't appreciate being handed over.
