Where do you find beldum on Pokemon Pearl?
Here's how you get Beldum on Pokemon Diamond/Pearl. First, talk
to Dawn's or the boy's sister each day until she says that wild
Beldum are swarming.She will tell you what lake or route they are
swarming at.That is ONE way to get it, the other way is by global
trading, which, on my account, is much easier. -Hope this helped
