Mr.Z
technically its not sam because there are 2 but if u put sams that makes much more sense
you can get 1 in at the mall and for the other one u have to get 40 cyberberries then go to the gift shop (donut museum) in R-fair city turn into chocoberry chiller (including 10 snelfus) then go to haunted hangout in castleblanca you'll find two-headed sam trade him and you have it.
I kmow that one is in the cybermall. check all 4 stores in the buy section NOT trade. Then you have to make another chocoberry chiller and give it to double headed sam in the haunted hangout and they'll give you the other cryoxide. Here is the way to get everything else: the cyberberries are in the 2nd area of r-fair city(can't miss it), on the way to manny's in aquari-yum, and the cybermall. all the other supplies are usually at the cybermall, so you really don't need to go anywhere else on a journey except to gain money from: manny(aquari-yum), the spokeswoman(r-fair city next to cyberberries), and both guys in mansion(castleblanca). hope I helped. thx
