SpongeBob SquarePants Season 4 Episode 14

When SpongeBob and Sandy arrived, the boat sank. But when they came out to leave, the boat was there again.

The inside of Gary's shell is much bigger in this episode.

In Pearl's song dream, in the crowd, there were the same people in each crowd, and the angels were already in the crowd.

In "Whale of a Birthday," there is no way that Mr. Krabs' credit card could buy that much stuff. The credit card shouldn't even last. Apparently, Mr. Krabs is a millionaire.

Sandy knocked off Master Udon off the the building, but when Squidward arrives, he's on the cliff, and back in his robe which he ripped off during his fight with Sandy.

In "Karate Island," when SpongeBob and Gary are inside Gary's shell, Gary has freckles. But he never had freckles before.

In "Karate Island," Sandy says she tought SpongeBob everything he knew about karate. However, when they met in "Tea at the Treedome," SpongeBob already knew karate.

In "Whale of a Birthday" after Squidward sings, a girl says this is a rip-off. How can that be a rip-off if no one paid to get in the party?

Master Udon says that Sandy must first pass 4 levels, but she only goes through 3.

Whale of a Birthday
How would Pearl's friend know that she had had 16 lame birthday parties in a row, because she wasn't at Pearl's other birthday party in the series in the episode Squeaky Boots.

Mr. Krabs must have well over one million dollars on his credit card, which indicates that he is a millionaire because:

- The Boys Who Cry band charges one million dollars just to show up.
- SpongeBob spent over $1,200 while shopping for Pearl.

This also can mean that all of Mr. Krabs' money are on his credit card, according to "Clams" (Mr. Krabs earned his millionth dollar in that episode).

It is revealed that Mr. Krabs has a credit card. His credit card number is 00012355587.

Whale of a Birthday:

When Pearl is leaving the Krusty Krab, she says "I am going to the mall with my friend!" to Mr. Krabs. When she gets to the mall, she is with 3 friends. She said she was going to be with 1 friend, not 3.

A rather adult joke appears during the first obstacle in the episode "Karate Island." The French fish who fights Sandy calls himself the "The Tickler". If you add the obvious French stereotype with the word tickler you get: French Tickler, which is a condom. A very subtle and explicit joke probably put in by the creators or it was just mere coincidence.

When Sandy is throwing jelly donuts in one of the guard's mouth, that plate starts out full, and then it starts to get empty. But then when it shows the plate again, it's full.

On the second floor of the karate tower, Sandy uses a hairdryer with a clearly apparent power cord; however, the walls are padded, there are no outlets.
