I found my Geodude in the Safari Zone. I am pretty sure you can also catch them in all of the caves, but I may be wrong. To get Geodude in the Safari Zone you walk into the Safari Zone Building and talk to Baboa. He'll talk to you about a challenge, in this challenge he'll ask you to catch a geodude. He'll tell you where they are, just search around a while and you'll find one. Have a good amount of Safari Balls left because I had to go in again because when I found one I ran out of balls before I caught it. Hope this helps.
Arbok can not evolve into any other Pokemon. Hope this helps.

Magby evolves with a happiness stat of 220 or higher, which should be reached at level 50 at the latest. However, happiness reverts to 70 when it is traded.
Each Pokemon is different and not all evolve because they have reached a specific level (some evolve due to high friendship, being traded, getting an item used on them, etc.). Some Pokemon that evolve through level will evolve between levels 10 and 20, and some may not have their first evolution until the late 30s. Also, not all Pokemon evolve. If you want a very accurate, satisfying answer, you will need to ask about a specific Pokemon.
