In the anime, occasionally Pokémon know moves they cannot learn legitimately in any of the games. It is unknown whether these instances are actual mistakes, a writing policy of not having to stick to the games too closely, or merely the Pokémon using an attribute that shares the name of a move in the games. In Bulbasaur... the Ambassador!, Professor Oak states that in times of need, Pokémon can call upon power that had never been known to them previously, such as Ash's Bulbasaur learning Dig.
This was a dubbing error, as Whirlwind's Japanese name is ふきとばし Blow Away. Ash was telling Bulbasaur to simply "blow it away" in the Japanese version rather than commanding the actual move.
Being a wild Pokémon, this Surskit's attack was not identified out loud in either the original or dub version of Dewpider Ascending!. However, the English version's closed captions identified the move as Tackle.
Ash's Starly used Gust in this episode. However, Starly was unable to learn Gust until Pokémon Legends: Arceus. It was changed to Whirlwind in the dub, a move that Starly could learn at the time. However, after it evolved into Staravia, it began using Gust in the dub as well.
Quick Attack in the Japanese version, a move that Vulpix can learn. Vulpix was unable to learn Agility prior to Generation VIII. The move was used in both versions of Hot Matches!.
