9. Arnold's bedroom
Series: Hey Arnold!
Pure fact: back in the day every avid Nickelodeon watcher wished they had Arnold's bedroom. Hell, we still want it today. Among the amenities: that dope ass skylight with the dimmer, jazz club-esque lights, the couch that rotated out of the wall and the remote that controlled all of that and more. Did we mention it's only accessible by crawl space ladder?
This is all without mentioning that he lived in a pretty interesting building overall. As owned by his grandparents, there various tenants were weird yet cool, and he also had the coolest pet ever in Abner the pig.
