>>54454101Ignoring the fact that Smack Down has only ever been depicted with a rock being launched, even by Pokemon like Dwebble who literally have no hands, "smacking" only implies sudden force. Yeah, it CAN be done with a hand, but its also used as "smacking into" things.
Tinkaton, a Pokemon that could only logically harass flying Pokemon with projectiles it makes or finds, not learning the move that knocks flying Pokemon down makes barely more sense than Regigias, the Pokemon found sleeping, not learning Rest until recently.
