croagunk evolves at level 37
To obtain crogunk, go to the Pastoria Great Marsh. Crogunk is one of the 14 Pokemon in the marsh who changes the area in which you find them each day. Head upstairs to the observatory room and peer through a telescope. It may show Crogunk in a picture over a certain area in the marsh. Head there and you will find him occasionally. To make sure that you are in the right area to find him, look for a landmark when sighting him/her in the telescope. Ex: rock,tree, bush, pedestrians and so forth.If you have trouble cathing crogunk, just stay in that area, and keep trying. Never throw mud or bait at him/her for he/she usually flees. Just keep throwing safari balls at him/her and eventually you will succeed!
Croagunk will evolve into Toxicroak at level 37.
to stop him from advancing on girls, misty pulled his ear in the kanto and johto series and max pulled his ear in hoenn, crogunk is merely taking the role of these two characters on sinnoh.
