in the desert
As far as I know there are only Ruby, Sapphire, Emerald, FR and LG.However, if you ask me, its either Ruby Sapphire or Emerald, where you can catch a Sandslash at lvl 23 in the desert. I don't know though if you can catch any higher level Sandslash'es in FR and LG.Hope I helped.;)
Sandslash evolves from sandshrew.
Nowhere.
Sandslash learns Dig at level 30 in Pokemon X and Y. In Pokemon Omega Ruby and Alpha Sapphire, it can learn Dig at level 33.
Yes, Sandslash can learn Dig at level 30 in Pokemon X and Y and level 33 in Omega Ruby and Alpha Sapphire.
How do you catch latios in Pokemon sapphire
Can't catch zapdos in sapphire
Yes, Sandslash can learn Dig by leveling up to level 30. It's level 33 in Pokemon Omega Ruby and Alpha Sapphire.
i dont think you can catch it in sapphire
You can't catch groudon in sapphire only in ruby. To get him in sapphire you have to trade him from ruby to sapphire.
You can't catch Bellsprout in Sapphire. You have to trade it from LeafGreen.
