Moshis vs Ghosts was an event in Moshi Monsters, themed for Halloween. The event began on October 17th 2013 but was confirmed on October 7th where an image was posted on the homepage. It is unknown when it will finish but it may be permanent, like the Great Moshi Beanstalk. You can access Moshis vs Ghosts by visiting Goosebump Manor. You get Ecto Gloops when you are blasting ghosts, but you only get one Ecto Gloop if you use the sweep ability.
