In the very ending of "The Wreck of the Mauna Loa", SpongeBob and Patrick actually find the REAL Mauna Loa.
SpongeBob: That was awesome!
Patrick: Yeah! Totally realistic!
Tyler: Realistic? That realism nearly cost us our lives!
Abigail: Mr. Krabs put all our lives in danger with this killest contraption!
Nazz: What were you thinking? Our little boy could've been hurt on your disaster of a ride!
Mr. Krabs: Okay, people, let's not do anything we might regret!
Officer Fish: Too late for that, Krabs. (handcuffs him)
Mr. Krabs: What—what—what are you talking about? You can't take me to the pokey! I--
Officer Fish: For operating a danger to public safety, I can and I will. Honestly, I think he'll be safer in prison.
Old Lady: And that's when I said it don't smell that bad, but it tastes...SpongeBob: Shut up, old lady!
This is the third time SpongeBob and Patrick be pirates. The first being "Arrgh!" and the second being "Grandpappy the Pirate".
Squidward calling SpongeBob "porous freak" is what Plankton called him in the episode "Plankton!"
This the the third time someone wore a costume to promote the Krusty Krab. The first was "Bossy Boots" and the second was "Krusty Sponge."
This is the second episode where the Krusty Krab sells something other than krabby patties, the first being "Pizza Delivery."
The title may be a parody of "The Wreck of the Edmund Fitzgerald" that sank in Lake Superior in 1975.
In real life, Mauna Loa is actually the largest volcano in the world. There was also an actual ship called the S.S. Mauna Loa which sunk.
