So Near, Yet So Farfetch'd - S1-E47
Continuity mistake: When Team Rocket takes off in the boat, it sinks. Their pokeballs float away, and Jessie says "Arbok and Lickitung are floating away!" But she doesn't catch Lickitung until Princess Versus Princess (Season 1, Episode 52).
Suggested correction: It's because these episodes were aired out of order.
That's true because of Electric Soldier Porygon.

(00:09:48)
Island of the Giant Pokemon - S1-E17
Continuity mistake: When Jessie says, "Well, you can use a good workout," the window frame in front of her and James is black, but in the next shot, it is instantly cream. (00:13:31)
Continuity mistake: Jessie seems completely surprised when she's told that Voltorb can explode, but in The Ninja-Pokemon Showdown (Season 1, Episode 32), not only did she and the others find out what Voltorb are, they were all affected by the explosions as well.
Continuity mistake: In both "Attack of the Prehistoric Pokémon" and "Charizard Chills", Charizard carries Ash on his back without any trouble. However, later on in "Charizard's Burning Ambitions", Ash is suddenly too heavy for Charizard to carry.
