One of the best shows, with one of the best openings. Hey Arnold! explores the lives of Arnold Shortman and his diverse group of friends, including Helga, who secretly has a crush on him. Each episode delves into childhood experiences, from school adventures to neighborhood mysteries that we can all relate to as kids.

One of the unique things in Hey Arnold! is that all the minor characters in the series have their own arcs and episodes, a brilliant idea to keep the viewers hooked to the series.

Danny Phantom centers on Danny Fenton, a teenage boy who gains ghostly superpowers after crossing a portal into the netherworld. Alongside his friends, Danny works as a superhero by saving his hometown from paranormal attacks with his newfound power.

#5. Rugrats

There’s a reason why Rugrats is considered one of the best animated series on Nickelodeon. The legendary series focuses on a group of toddlers: Tommy Pickles, Chuckie Finster, and twins Phil and Lil DeVille. 

Through Rugrats, we got to see the vibrant world through the eyes of these curious infants as they embark on various escapades, often fueled by their vivid imaginations. Angelica, the only main adult in the show, is also an aspect that made Rugrats much more interesting and diverse.


#4. The Fairly OddParents

The series introduces us to the young miserable boy Timmy Turner, whose life takes a fantastical turn when he is granted two fairy godparents, Cosmo and Wanda, who can grant his every wish. While Timmy's wishes often lead to hilariously unintended consequences, the show explores the importance of responsibility and the enduring bond between friends.


#3. iCarly

Easily one of the best teen sitcoms there is. iCarly follows the story of Carly Shay, who, along with her friends Sam and Freddie, starts her own web show, "iCarly." The trio produces and hosts a web series that quickly gains popularity, leading to hilarious misadventures and memorable moments.

And, like many others, Carly has to find the tranquility between her celebrity work and her normal daily life. It’s a show with a lot of hilarity and struggle of the adolescent age that we can all relate to, which is why the young audience falls in love with it so much. A rebooted series was aired recently, but obviously cannot match the success of its predecessor.


#2. Avatar: The Last Airbender

A combination of both stunning animation and gripping story from start to end, Avatar: The Last Airbender is a masterpiece of its own category. Following Aang, Katara, and Sokka on their adventure to stop the Fire Nation invasion, the animated series treats us to groundbreaking bending battles (literally), diverse Asian culture, bittersweet romances, and a deep and rich story that is way darker than what we anticipated.

Avatar: The Last Airbender is so good, the series has a cult following of its own, and is deemed one of the best animated series ever. Its sequel, The Legend of Korra is also in a league of its own, but still can’t hold a candle to the original one.


#1. SpongeBob Squarepants

Without a doubt, Spongebob is the most iconic show on Nickelodeon, and one of the best in history. The series itself is a bizarre whack-fest that is full of absurd and eccentric characters who live in Bikini Bottom: a sponge, a talking starfish, a squirrel wearing a diving suit, and a grumpy octopus who hates his neighbors. 

In each episode, SpongeBob SquarePants treats us to a brand-new whacky adventure that never fails to catch us off guard. It is the absurd hilarity and unorthodox characters that make the show into a pop culture phenomenon. Therefore, in our opinion, Spongebob Squarepants totally deserves the top spot on this list.



Old Nickelodeon shows, especially in the 2000s era, have been an integral part of our childhood. And even now, when we watch them again as an adult, the sensation and feeling when seeing our favorite characters still stay the same. 

We certainly hope that this list of ours will help you revisit some of your best childhood memories with these films. Don’t forget to follow us for even more intriguing Nickelodeon articles.
