"Sandy's Rocket" and "Squeaky Boots" are episodes of SpongeBob SquarePants from Season 1.
It's hard to write entries about SpongeBob airings because I feel like 99.5% of people coming to my site have seen plenty of the show. Everybody knows these classic episodes so I can't really give my two cents on them without rehashing what everybody else has said for the last 20+ years.
Something interesting that I'll bet most people aren't aware of is that "Squeaky Boots" is actually the second-oldest produced episode, despite airing near the middle of the first season. While its sister-episode "Sandy's Rocket" has a production code of 110 (indicating it's the tenth episode of the series produced) "Squeaky Boots"' production code is 102. The only episodes produced earlier than it are "Tea at the Treedome" as well as the unaired 1997 pilot of SpongeBob, though it doesn't have a production code. The version of the pilot that later aired on Nickelodeon as "Help Wanted" has a production code of 127, indicating it was revised much later than a handful of episodes were produced for Season 1.
Unfortunately, no commercials from this airing have survived so I've embedded the title card to "Sandy's Rocket" as a placeholder. Credit to YouTube user AreaEightyNine for uploading it.
