Gluttony
Makes the Pokémon eat a held Berry when its HP drops to half or less, which is sooner than usual.
Own Tempo
The Pokémon sticks to its own tempo, preventing it from becoming confused or being affected by Intimidate.
It gives off a stimulating scent because of chemicals that have seeped into its body from the spice that it eats as its staple food.
It uses its tail to fish, but the scent of the spice emanating from its tail ensures its catches are always lacking.
