Doesn't look like it at the moment. I found the comment I referred to earlier, I can't link to it directly but...
On the OWI Facebook page there are three pics uploaded of the scuba toad model in game. For the one which is a long shot, and the toad is very small behind a Clakker, someone asked what he does in game. OWI replied that he moves around, but is not for the PS3 or Vita versions, so I guess it's a PC exclusive.
Unless the scuba toads are being included as some kind of incentive for that platform (such as 'thanks for waiting a little longer for SWHD, here's some extra content') then I cannot see why it wouldn't (or maybe that should be couldn't) be added to the PS3 version.
