The Snowball Effect / One Krabs Trash - S3-E3
Corrected entry: How does Squidward get to the top of his snow fort if there's no stairs on the inside of it, not fall inside the snow fort without holding on? How does it snow underwater, and where did that big tree come from?
Correction: Remember: Squidward has six limbs (including arms). He could have been holding on to the sides of the fort. Besides, we don't know how long it took him to build the fort. As for the tree, common cartoon humor.

Corrected entry: Squidward's fireplace was behind Squidward early in the episode, but later on when Squidward throws a snowball and misses Spongebob and Patrick, it's in front of him.
The Snowball Effect / One Krabs Trash - S3-E3
Corrected entry: A clarinet of that length couldn't be perfectly hidden inside a snowball that's about one quarter the size.
Correction: It's a joke to show how seriously Squidward is taking the snowball fight. (Patrick even says so).
Correction: IT'S A CARTOON! Some suspension of disbelief is expected. Sea creatures don't talk or wear clothes either.
