I have emerald and I have found geodude, torkoal and koffing. There is also graveler, murk and grimer. Possibly there could be slugma and numel. Evolutions of slugma and numel are rare. Catch when possible.

The only way to get a camerupt is to evolve your numel at lvl 33. The only way you can catch Numel is in Ilex Forest, using 'hoenn' music. For this you'll need GBA sounds and the radio app. In Diamond/Pearl/Platinum you can get a numel on route 227. If you still can't get one, you could always ask a friend to trade you one. Good Luck. Hope this helps :D

There are many Pokemon you catch that are similar in sapphire and emerald but there are many Pokemon emerald can only get and not sapphire.
Cressilia is a 4th generation Pokemon so you can't catch it in Pokemon Emerald.
You can't catch or obtain other trainers Pokemon in emerald.
In the grass below the ski lift, you can find numels. If you have a bashful Pokemon that has the ability of synchronise then you have a larger chance of finding a numel with a bashful nature.
