The Big One
The Big One is a giant wave seen in the episode SpongeBob SquarePants vs. The Big One. It is apparently alive as it has eyes and a mouth.
The Big One always demands a sacrifice from everbody who tries to ride it. List of things sacrificed:
- Patrick's and Squidward's surfboard.
- Cashy (But later returned)
- Jack Kahuna Laguna (But later returned)
The Big One is very hard to ride and laughs when you come up to it. This is quite odd because it is not really a being, it is just a wave.
The Big One is just a huge water wave with a face and tongue made of water. Once it smiled and ate Patrick's surfboard.
 Times it comes
Every year ending in -009, e.g. AD 1009. The Big One appears when all the planets in the solar system line up.
