Lowers the effectiveness of Bug-type moves on the user by one level for one round. One use per battle.
This green, lobed berry grows on a bush that is pollinated by insect Pokémon. A Pokémon holding this item may consume it to reduce the effectiveness of Bug-type attacks made against it by one stage for one round. (Thus, a 2× weakness to Bug would become a 1.5× weakness to Bug for one full round after a Tanga Berry was consumed.)
