How do you catch Marill on Pokemon Silver?

first go to Ecrutek city then go to the right and fine a cave but go to route 45 and get the phone of the hiker name parry then he will call you that there are so many Marill in the cave

TIP:Get a Poke'mon know flash

TIP:Don't surf on the water

Okay, I have some helpful information. Marill is only found at the entrance of the cave. The odds of finding one is 1 in 100 or 1%. I counted 95 pokemon before I finally found Marill. You can also follow the instructions above, but some of us don't want to wait for a phone call. Just remember what I said about marill only being at the entrance. So just enter the cave and walk back and forth. I hope this helps others.
