Pokemon HG/SS Safari Zone

Okay, so, I've figured out how to find some of the Pokemon in the Safari Zone like Zangoose but I'm struggling to find Pokemon like Bagon. Bulbapedia didn't really make much sense to me about it, could someone perhaps explain how it works or at least explain the method for making the following Pokemon appear in the Safari Zone (mostly how do I use the right objects on the terrain):

Cacturne
Beldum/Metang
Bagon/Shellgon

Thanks in advance.

 

It took me a while to figure out too, but the way Bulbapedia organizes it is by Area.
So to get a Cacturne, make one of the Safari Zone tiles Desert, then put only Waterside objects there, with a total point count of 42. I think you need to get a block upgrade to get Cacturne though, so you may be better off getting a Cacnea using Forest blocks instead, which still requires a block upgrade but fewer points.
Cacturne can also be found in the Savannah area with 35 Forest points.

Beldum is available in the Peak Tile, with 63 points in blocks. You can also get it on the Pokewalker's Winner's Path after 8000 steps.

Bagon can be found in the Swamp Tile, with blocks Peak Pokemon like, totalling in 52 points, and Forest Pokemon like, totalling in 35 points.

The objects (blocks) all have descriptions, like "Waterside Pokemon seem to like it best, etc.", and that's how you know what type it is.

 

Thanks. That's made a lot of sense and I think I can understand the table now. I'll try Winter's Path for Beldum anyway :lolface:
