King's Rock
From Pixelmon Wiki
A King's Rock is a held item that causes the holder's damaging attacks to have a 10% chance of causing the opponent to flinch. This effect does not stack with moves that already have a chance to flinch. It can be obtained as a drop from Boss Pokémon.
A King's Rock can also evolve Poliwhirl into Politoed if Poliwhirl holds it while being traded. The King's Rock will be consumed in the process.

- Poliwhirl cannot evolve into Politoed even if the evolution method is executed correctly.
