Astrology with Squidward (found series of "SpongeBob SquarePants" Nickelodeon animated short series; early 2000s)
In 2000, Nickelodeon decided to start airing a spin-off to the currently popular SpongeBob Squarepants TV Show called Astrology with Squidward. The show was basically a series of shorts where on different times of the year, Squidward Tentacles would come in and explain the different parts of the Zodiac. The Zodiac symbols that are represented in the shorts however, are mostly just crudely designed versions of the main characters like SpongeBob as Sagittarius, and Patrick as Taurus, while Mr. Krabs is his normal design as Cancer, and two Ambulance Fish are represented in their normal design as Gemini.
Despite the shorts becoming as popular as its predecessor, Nickelodeon made the decision to pull them from the air around 2001. Even though today the shorts are rarely broadcasted on Nicktoons, several of the original English recordings of the shorts, and two of the shorts themselves are considered missing. All we have left of the shorts today are three with their original English dub, and three that are Russian dubbed (albeit in better quality than that of the English shorts that have re-surfaced). The two shorts that are completely missing are Libra (Squidward) and Virgo (Pearl).
UPDATE Dec 29, 2013: Today, Redditor SickFinga translated the three Russian shorts and the transcripts are available here. Later that day, Lost Media Wiki user bun39 uploaded the Russian dubs of the episodes with English subtitles in .mov format to mega.co.nz.
