The Unova starters are Snivy, Tepig and Oshawott, introduced in Pokemon Black and White in 2010 as the first partner Pokemon of the Unova region. Short slap clips using Pokemon characters spread through soundboards and short form video edits, where a name that combines the Pokemon, region and action makes the effect easy to find and reuse. This clip stays popular because the hit is instant and readable even without context, so creators reuse it for Pokemon memes and for general cartoon slap jokes beyond the games and anime.
