The folks at Diamond Select Toys will be releasing two variants of their Ghostbusters Stay Puft Marshmallow Man bank. One will be a glow-in-the-dark blue variant (similar to the Minimate they did for San Diego Comic Con). You can check out an early prototype of this one below but it should be noted the had will be different from what is shown here. The actual production piece will have the “happy” face.
The second variant is still being kept under wraps, but hopefully we should hear more on this in the near future.
