But the stories couldn't exist without those wonderfully slimy ghosts! Here is the super-haunting Slimer, just one of the Ghostbusters Ecto Ghosts, a delightful collection of slippery ectoplasm-y creatures. They offer fans hands-on opportunities to recreate scenes from the film and invent some of their own. These ghosts are full of squishy, ectoplasmic material. Squeeze them and watch slime ooze from their eyes and reveal floating eyeballs. They're funny, scary, and gross all at the same time! Along with Slimer, you can also collect Rat Ghost and Splitting Ghost for lots of slimy Ghostbusters fun!
