Bubblestand / Ripped Pants - S1-E1
Character mistake: Ripped Pants: During the opening credits, Paul Tibbitt's name is misspelled as "Paul Tibibitt" (it is spelled correctly the second time it is shown), and Mark O'Hare's name is misspelled as "Mark O'hare." (00:11:54)
Jellyfishing / Plankton! - S1-E3
Character mistake: In "Plankton" when Spongebob is in Plankton's lab, he says the ingredients in a Krabby Patty. He doesn't mention the secret sauce.
Help Wanted / Reef Blowers / Tea at the Treedome - S1-E2
Character mistake: In "Help Wanted", Stephen Hillenburg's name in the "Written By" section of the title card is incorrectly spelled as "Stephen Hilleburg."
Chosen answer: You need to provide a little bit more information to be able to answer a question like this. In what region is it not being shown? I see it being replayed here in Australia fairly frequently. As for a general reason, there does not appear to be any for why it specifically might have been taken off the air in any country or region. Like any show certain episodes can sometimes not be replayed for long periods for unknown reasons.
