New Oslo is a rural town located in upstate New York. 
In 1997, New Oslo was hit hard by a heat wave that led to drought. With crops on the line, a young boy named Swen Christianson foolishly used the Sceptre of Donar to call upon the Harasvelg for rain. Slimer later flew to New Oslo in secret to retrieve the Sceptre and help the Extreme Ghostbusters.
