Yes, I know, I think I have gone on a Real Ghostbusters rant a few times now
but, only one of the local Walmart stores seemed to get Wave 1 (along with Retro Star Wars), so I am hopeful that Slimer and Stay Puft show up at one or the other of them (or both!).
The listings for the RGB Wave 1 figures have been removed from the Walmart CA website as well. And to the best of my knowledge, they were never in stock there anyway.
Hoping all the re-issues get a re-issue sooner or later. In the meantime, hopefully Slimer and Stay Puft get better distribution.
