I found him while level grinding on the first route.

Literally route 1

>>30030627
1st route he just has a retardedly low encounter rate

I've been running in circles for 20 minutes now. this is hell

>>30030720
try encountering a marill in G/S.

now that is hell.

>>30030738
I'd rather catch a feebas in ruby at this point

>>30030738
I remember Marill had a rare catch rate in HGSS, was it worse back in GS?

>>30030720
There are two encounter pools for wild Pokemon on route 1. One of them is in the first couple patches of grass, and consists of level 2-4 yungoos, pikipeck, ledyba and caterpie. The other is in the patches of grass closer to Iki town, and has level 4-5 of the above monsters as well as grubbin.

I believe 1% if I'm not mistaken.

>>30030720
It'll be worth it once you catch it
Until you realize you can't even get Vikivolt until you reach Poni island

>>30030789
both have a 1% encounter rate in G/S/HG/SS

however, you can just use the safari zone or get a swarm in HG/SS to get a marill much more easily
