The scene was from Pokemon episode "The Evolution Solution" and the music is from the DBZ Faulconer soundtrack. There where many epic and funny scenes where we got to see Psyduck vs Team rocket, but this is one definitely stands out as one of psyduck greatest moments throughout the show.

Misty's Psyduck can easily be described as dimwitted and absent-minded. When it pops out of its Poké Ball, it often doesn't know how it got there. It is perpetually confused, and even when it summons powerful moves, it appears confused about how it pulled such a feat off. Its motivation for jumping out of its Poké Ball remains unknown, as it clearly does not enjoy or excel at battling. Even in the episode Just Add Water, it pushed Ash aside, wild with anger at Team Rocket's abduction of Misty (she had been captured saving him) and insisting on battling. However, after a few seconds, it completely forgot what it was doing and went back to looking confused.
