Evolve from Gulpin at level 26, who can be found in the safari zone.
To catch the Pokemon GULPIN, you need to fy (or walk!) to the Great Marsh. Then in area 6, there is a patch of swamp that measures 4 by 4 tiles (the tiles are located in a corner of trees, near the "Area 6" sign.) Walk around these tiles until you find GULPIN! P.S:I have 16 GULPIN's!!!
