Route 4 (after using Waterfall)

On the turn it's chosen, Sky Drop lifts the target into the air, rendering them unable to act. During this time, both the user and the target are immune to most moves but not to Gust, Thunder, Twister, Sky Uppercut, Hurricane, or Smack Down. The following turn, the target is dropped back to the ground and takes damage. Sky Drop doesn't harm Flying-type Pokémon but still suspends them. It can target distant Pokémon in Triple Battles and allies but fails when used on allies. No Guard, Lock-On, or Mind Reader allows moves to hit airborne Pokémon. Sky Drop fails against substitutes, semi-invulnerable targets, or those under effects like Fly or Bounce. It can't be used during Gravity, and if Gravity is activated during Sky Drop's semi-invulnerable turn, the move is canceled. In Generation V, a glitch can occur in Double and Triple Battles under these conditions. If a Pokémon using a consecutive move is lifted by Sky Drop, it stops using the move. Protect and Detect can guard against the initial use, but no moves, including Protect, can be used in the air. Sky Drop isn't affected by the Power Herb and won't consume it. It's also not redirected by Follow Me or Rage Powder, and if a Pokémon is airborne due to Sky Drop in a Rotation Battle, they'll be dropped into their new position, taking no damage.
