I think I can make a case that this episode is the best one of the whole series. Now, there are A LOT of good episodes, but everything is just so perfect in here. No Krabs or Plankton, so we don't have to worry about the episode being an entire Plankton scheme or "I-will-do-anything-to-get-money" episode. Squidward is used perfectly, as he isn't tortured and adds a solid amount of comedy while still being stuffy. I think Patrick and Sandy is an excellent and underused combo. You have a really smart character and a really stupid one who are both still very friendly and lovable. And Spongebob's antics are classic and I still laugh even after seeing the episode like 30 times. There's excellent writing, a definitive beginning, middle, and end. Pat and Sandy's antics are entertaining, and just the Sponge-Pat-Sandy combo is always really well put together. And the gorilla scene, despite being as random as it gets, is hilarious. It showed that spongebob would risk his life to save his friends. The Spongebob series in a nutshell is in this episode gem, random live action, comedy, silliness, classic lines, and perfect character usage.
