Marth Debuted in Smash Bros.: Despite Namco preferring to not speak about the unauthorized Bally Midway games (with the exception of Ms. Pac-Man, which was made official thanks to its success), that didn't stop their characters from appearing in official Pac-Man games. Japanese players would think that Junior got his beany propeller hat from Pac-Man 2, when he actually got it from Jr. Pac-Man, his starring role. There's also Professor Pac's appearance in Pac-Man World, when he originally came from Professor Pac-Man, minus the mustache.
The Danza: Susan Silo played Sue. Likely either an inversion or a coincidence, as the name "Sue" had been used for a ghost in the Ms. Pac-Man video game (although it was simply Clyde from the original with a different name).
Despite airing in 1982, the Hanna-Barbera series saw no VHS or DVD releases until January 2012, when the first season was released on DVD. The second season was released in September that same year. Both are available as manufacture-on-demand DVDs from the "Warner Archive" program, although they can also be bought via Amazon, eBay, and various other Internet auction sites.
In the 1980s, there actually were a number of VHS releases for the series...outside America.
