How do you get Scizor in a egg on Pokemon Diamond?

obviously, you can't catch scizor in Pokemon diamond. receiving an egg would be impossible. there are two egg locations wich is lucario and happiny. lucario is in the iron island that a character named RILEY is holding it. to receive it ], you have to be his partner and when your done helping him. he will give you an egg. Another egg is in the harthiome city. you receive it when you talk to the fatty guy when you are going in oreburg. he is standing there.... waiting. you must have one room for happiny. talk to him then...............voila. you receive an egg.

hope it helped
