I really want a dream world Regiice but have no idea how? HELP!!
Sorry to tell you this but Regice isn't available in Dream World right now.
It says so right here in the Ability section- http://www.serebii.net/pokedex-bw/378.shtml
You can get one by hacking a Regice with the DW ability, but i wouldn't recommend it.
Hope this helps =P
You cannot get it from the dream world. They get the abilities by hacking. So in sort terms, No.
