Croagunk resembles a dark blue bipedal frog, with a white band around its waist area and red and black markings on its hands and feet. Its coloring and poisonous nature suggest that it is based on poison dart frogs. The markings on its body make it look like a Muay Thai fighter, and its jutting teeth make it appear to be wearing a mouthguard. The black around its eyes and the white bands make it look like an injured fighter with black eyes and broken ribs. Its cheeks are filled with a poison that runs to its fingers, allowing it to poison opponents by stabbing them.
Gender differences
The two white stripes that run across Croagunk's abdomen will be higher up if it is a female.
Special abilities
Whenever its middle finger glows purple, it appears to be channeling its poison via its skin and onto its hand to use its Poison moves. Croagunk can have the ability Anticipation which makes the Croagunk shudder if the foe has a super effective, instant KOing move, or a move like Selfdestruct.
Behavior
Croagunk are generally mischevous and mean. A few Croagunk, however are more comfortable being alone, simply staring at the views around them.
Habitat
Croagunk live in moist areas close to bodies of water.
Pokémon Mystery Dungeon 2: Croagunk is one of the members of Wigglytuff Guild. He doesn't have much of a purpose other than to run the Swap Cauldron. His catchphrase is Meh-heh-heh.

Croagunk's English name, along with numerous others, was released on 13th February 2007. Due to the poor quality of the image, it was believed its name was "Croalurk".
Croagunk and its evolution are the only Pokémon to have the Poison/Fightingtype combination, and as such, they are the only Pokémon to have a double weakness to Psychic attacks and are the only Poison-types to have any double weakness.
Croagunk is one of few Pokémon to have its hand-held game sprite differ from its 3-D image. While in Pokémon Diamond, Pearl, and Platinum it is shown to have pink cheeks, its 3-D models show it with yellow-orange cheeks.
Despite having "gunk" in its name, it can only learn Gunk Shot through the move tutor in Platinum.
In Platinum, on occasions at the Pastoria Great Marsh, if the player stands behind the Croagunk Wall with the their head sticking out of it, a wild Croagunk will come by and walk into the Great Marsh building.
Croagunk is probably a combination of croak and gunk. It also sounds very similar to shogun. The Japanese name comes ケロケロ kerokero, the Japanese onomatopoeia for a frog's croaking, and げろげろ gerogero, the Japanese word that's used to describe something disgusting. It may also be derived from 汚れ yogore, filth.
