Buster Baxter & the Letter from the Sea

Summary
While on vacation with the Read family, Buster discovers a message in a bottle on the shore.

Plot
The episode starts off with Captain Jack waking up in Antarctica, floating on a chunk of ice. Realizing that the boat he was on is leaving without him, he writes a rescue letter and puts it into an empty bottle of grape cola, then throwing it into the ocean. A penguin then comes to the chunk of ice that he is on and gives him a fish, and he smiles. As time goes on, progressing to the present, Buster claims that he found a treasure on the beach.

Trivia

 * All fantasies in this episode use a different transition effect than usual. It consists of rising bubbles (similar to the scene transitions used on SpongeBob SquarePants) and a ripple effect similar to the one used in The Contest.
 * This is the final time the "Arthur Underwater" title card is used in the U.S.
 * This episode was originally going to have a scene where the underwater kingdom was approached by a huge tidal wave. It was cut back due to the fear that it would give kids anxiety, or because of the tsunami in mainland southeast Asia in 2004.
 * This is the first episode in which George narrates the title card.

Episode connections

 * After Buster and Arthur read the letter, El Boomerang from "Follow the Bouncing Ball" appears.

Cultural references

 * Buster makes a reference by asking in one of his letters, "Do octopuses really have gardens?"

Errors

 * When Buster wakes up from a dream, he is wearing his blue vacation apparel.
 * In the opening, it says that the episode took place in 2012, but later the captain says that the letter was 51 years old and it was written in 1960, which means the episode actually took place in 2011.
