Gen IV of the Pokémon series introduced a variety of new Pokémon, making a return in Pokémon Brilliant Diamond and Shining Pearl. One such Pokémon is Croagunk and its evolution, Toxicroak. You might be wondering where to find Croagunk in Pokémon Brilliant Diamond and Shining Pearl.
You can find Croagunk in two places. Normally you can only find it in the Great Marsh in Pastoria City. But in the remasters, you can also find Croagunk in the Grand Underground. You can find Croagunk in Bogsunk Cavern, Riverbank Cavern, Still-Water Cavern, and Swampy Cave Pokemon hideaways.
Croagunk and Toxicroak feature a unique poison-fighting typing that no other Pokémon line has. This gives them a wide range of coverage but unfortunately leaves them extremely vulnerable to the psychic type.
Toxicroak has a decent balance of stats, with attack being its best. If you are looking to fill a poison or fighting-type slot on your team, Toxicroak would be a good choice, especially if you are a fan of amphibians.
