Teatime causes all Pokémon on the field to eat their held Berry. This move bypasses substitutes.
If a Pokémon has eaten its Berry, Teatime fails to work on that Pokémon. The Berry is eaten even if it would not have any effect, such as eating a Mago Berry at full health. If no Pokémon on the field has a held Berry, Teatime fails with the message "But nothing happened!". Teatime causes Pokémon to eat their Berries even in the presence of Unnerve or Magic Room. This move does not affect Pokémon under the effect of Max Guard.
Pokémon in the semi-invulnerable turn of a move are not affected by Teatime. If Teatime has its type changed by Electrify or Plasma Fists, Pokémon with Volt Absorb, Lightning Rod or Motor Drive will not use up their Berries but will instead gain the benefit of the Ability regardless of whether they are holding a Berry or not.
