Gulpin

Sticky Hold : This Pokémon's hold item cannot be removed by other Pokémon. Damaging moves that would remove this Pokémon's item can still inflict damage against this Pokémon, e.g. Knock Off or Pluck. This Pokémon can still use moves that involve the loss of its own item, e.g. Fling or Trick. Overworld: If the lead Pokémon has this ability, the encounter rate while fishing is increased.

Liquid Ooze : Whenever a Pokémon would heal after hitting this Pokémon with a leeching move like Absorb, it instead loses as many HP as it would usually gain. Dream Eater is unaffected.

Gluttony : This Pokémon eats any held Berry triggered by low HP when it falls below 50% of its HP, regardless of the Berry's usual threshold.
