Worry Seed (move)

Worry Seed changes the target's Ability to Insomnia. If a Pokémon affected by Worry Seed is switched out, it regains its original Ability.

Worry Seed fails if the target's Ability is Truant, Multitype, Stance Change, Schooling, Comatose, Shields Down, Disguise, RKS System, or Battle Bond. It also fails if the target's ability is already Insomnia.

With this effect, the target Pokémon cannot sleep and wakes up if already asleep.
