Going by a post made by the Ghostbusters of the Ozarks, it looks like Mattel has been emailing Club Ecto-1 members to let them know what their promised thank you gift will be – based on a Slimer figure produced to go along with an SDCC exclusive Egon from 2009, those holding a now defunct membership will receive a glow-in-the-dark Slimer. He’s about 2.5 inches in size and comes with a stand. As previously mentioned by Mattel, he’ll come loose in a bag, not boxed or carded.
