- SpongeBob SquarePants
- Realistic Fish Head
- Patrick Star
- Eugene H. Krabs (cameo)
- Squidward Tentacles (cameo)
The Realistic Fish Head starts off the short by saying "Attention! SpongeBob needs your help to protect all others," and the short starts to tell some simple ways that SpongeBob can save the Big Blue.
- Stock footage is used from the episodes "Boating School," "SpongeBob Meets the Strangler," "Sand Castles in the Sand," and "SpongeBob SquarePants vs. The Big One."
- The short was made for Nickelodeon's educational project The Big Green Help.
- The website (http://www.nick.com/biggreenhelp) mentioned in the outro does not exist anymore because the educational project ended in 2009. The link is now a redirect to the main Nickelodeon website.
- There are four things on the list, but only three of them were mentioned.
- The only hint of the fourth thing that is on the checklist is a plant in a pot.
