They're high levels because Metang was caught from the wild (Giant Chasm, Bulbapedia confirms it), and the Munchlax was traded within the game.
I have the Black version. However I'm having trouble breeding them to a lower level, so you are probably better off asking Ezio-X to help you.

Are you still looking for the five pokemon in the quick trade thread...?

If so, I can breed you all of them for nothing.... Just trade crap pokemon you dont want....

Why the high levels? Are they legit?

And yeah, I'm interested in the Metang, preferably Beldum but the Metang will do. Same with the Munchlax. Lower levels preferred, so if you could breed me up one of each that would be awesome! If not that would be awesome too!!

Do you have Black or White? I finally got a Timburr and evolved it and now I just need someone to trade with to get it to a Conkeldurr.

I have a lv. 16 Timburr and a lv. 65 Metang (which I can breed to get a Beldum) and a lv. 60 Munchlax (which can be bred if levels are too high.)
I want some Pokemon in my SoulSilver to be evolved via. trade, in return. Let me know if you're interested.
I'll be on for another 30mins then I'll be going to bed.
