Explanation: 

The story carries moderate tragic elements, particularly with the harrowing description of a world devastated by an ancient catastrophe, the destruction of underwater communities, and the immense losses faced by the sea's inhabitants. However, these tragic elements are not explored deeply enough to merit a higher score. Therefore, the Tragedy Degree is given a 4.

Regarding the Comedy Degree, while the inclusion of SpongeBob SquarePants adds a light-hearted and whimsical element, the story itself does not contain significant comedic plots or a joyous resolution. The tale focuses more on the serious message of environmental awareness than comedic aspects. Therefore, the Comedy Degree is given a score of 3.
