Astrology with Squidward is a 2000's Nickelodeon series of six interstitial shorts where, during different times of the year, Squidward Tentacles would explain the different parts of the zodiac. Most of the zodiac symbols that are represented in the shorts, however, are just crudely designed versions of the main characters (like SpongeBob as Sagittarius and Patrick as Taurus), although Mr. Krabs, the Ambulance Fish, and Sandals are represented in their normal designs.
Despite the shorts becoming nearly as popular as its predecessor, Nickelodeon made the decision to pull them from the air on Nick in 2001 but later reappeared on their sister channel, Nicktoons, in 2002, where they continued to enjoy airtime up until 2005.
There have been rumors that two shorts, Virgo and Libra, were created, but this was debunked by Vincent Waller on Twitter, https://twitter.com/VincentWaller72/status/1115320898297290752
Six surviving, original English-dubbed shorts, five surviving Russian-dubbed shorts and two surviving Polish-dubbed shorts are below.

May 29, 2016: Lost Media Forum User AniMount posted some information about the lost shorts. The information described maybe true/false. Keep it in mind: I remember watching it when I was 5. I would like to give out all of the information I remember about the lost episodes.
Virga. As far as I remember Squidward said that "They will ask their parents for some money".
Libra. I actually don't remember anything about it but I still have some small info. On the picture (that is right to Squidward) was Squidward in his intro pose (In the start of any episode)
Scorpio. German Nickelodeon wiki says it exist and I can say IT (probably) EXISTS. I am not sure who was Scorpio, but all I can say IT probably exists.
P.S. I don't think Capricorn and Aries exist.
I hope I helped a bit!~~
June 25, 2016: I translated a German Nick wiki
☀(http://de.nickelodeon.wikia.com/wiki/Dein_Horoskop_mit_Thadd%C3%A4us) and found out Plankton was represented for Scorpio (also for Leo).
