"SpongeBob SquarePants" has a unique cast of characters, and each one can be found within your friend group.
For starters,There is always someone who is, basically, SpongeBob. This person is usually the one who can make everyone laugh. They may come off as childlike, but that is just because they can never quit laughing. They are able to make everyone get along and always have a smile on their face.
There is also a Patrick Star found in every friend group. This person is the best sidekick out there. They are there to reinforce everything you say, and they always have your back. They can make you laugh at just about anything, but they may come off as stupid every now and then. No matter what, though, this person will always be your best pal.
Gary can be found in your friend group, as well. If you are like Gary, you are very quiet and soft spoken. This person may be very shy, but they always stick around for the good and bad.
Everyone knows which friend in your group is Squidward, who is always in a bad mood and always has something to complain about. He usually acts like he hates everyone and everything, but deep down he really does appreciate and love you, even if it doesn't seem that way.
Then there is Sandy Cheeks. Sandy is the person who is a lot different from everyone else, but everyone loves her anyway. Everyone is very drawn to this person, but she gets homesick quite often.
Miss Puff is the mom of the group. They are always able to keep everyone in line, and everyone usually goes to them for advice. This person is definitely one of the best friends to have.
And finally, there is Fish #1. This guy is always around, and nobody can ever figure out why. He just always ends up showing up no matter where you are, and no one even knows his name. This person may freak you out, every now and then, but they are harmless.
I am sure you could name a few people you know that represent each one of these notorious SpongeBob characters. Honestly, without these people, your friend group would definitely be missing something.
