I will be in Las Vegas Next Week, Where is the Cool Monster Stuff!?

[Neoplastic]

I will be in Vegas next week and wanted advice on any stores or attractions involving monsters.  I thought I would visit the Toy Shack on Fremont but I am clueless as to other places that would have cool monster stuff.  Thanks for your help.
