I can't find dedenne on route 3 or a moon stone in goldenleaf. Help. Please

[Abyawn]

I need a dedenne for a strategy to beat the giratina battle (found it on the discord) and a moon stone, someone said there is a moon stone in goldenleaf (the guys backyard) but all I found was a rare candy. (V13)

If possible please attach pictures of the moon stone.

Dedenne is not on route 3, but on route 2 (1% in daytime) and the moon stone is located in the red circle (picture)
