"Dr. N. Sane's Home for the Mentally Unfit" is the name of a psychiatric hospital, owned and operated by Dr. N. Sane. Sprinkles and Jack, along with many of their enemies, have been incarcerated there.
Initial Era[]
The mental institution first appears (in the Initial Era) in "Sprinkles the Psychotic Moose" Volume 1, Number 4. Sprinkles and Jack were taken there, and subsequently battled Captain Nutso and Spunky (who were also held there) and the Newer Fantastic 5. Part of the building explodes in "Sprinkles and Jack" Number 1 from a time bomb planted by Nutso before he and Spunky escaped.
As mentioned in The Adventures of Sprinkles the Psychotic Moose Number 11, the Home has been in business at least since the early 1970s.
Digital Era[]
In the Digital Era, Dr. N. Sane's Home for the Mentally Unfit appeared in "Sprinkles the Psychotic Moose" Volume 2, Number 1 (2008). Buckethead was being held there, and Dr. N. Sane was trying to make progress with him, regarding his obsession with Martin Lewis.
