At the CN YMCA is an animated web-series exclusive on the Cartoon Network 2 website. It's a crossover about the characters of 7 of the newest cartoon network shows hanging out at a YMCA-type recreation center called the CN YMCA. The main characters are Finn, Jake, Mordecai, and Rigby who work at the CN YMCA and regularly interact with the other characters who normally come to visit. Other characters include those from Adventure Time, Regular Show, Uncle Grandpa, Clarence, Steven Universe, Teen Titans Go, and the Amazing World of Gumball. Together they have lots of fun working together and solving crazy problems on a regular basis like Mordecai and Rigby accidentally getting turned into 5-year-olds by Uncle Grandpa or getting snowed in on summer vacation after the Ice King tried making snow-cones for everyone.




Finn is a 15-year-old human boy from Adventure Time who works at the CN YMCA as supervisor. He likes helping people and is always willing to help his friends whenever he can. No matter how small the problem may be. Although he's the youngest, he is also the second most mature. He also has problems with love since he says Valentine's Day makes him "feel weird."


Jake is a 30-year-old yellow dog from Adventure Time with "stretchy" abilities that let him change the shape and size of his body at will. He works at the CN YMCA as a cook, which is no surprise since he can cook really well. He doesn't usually use a cookbook and will usually use his own recipes such as Bacon Pancakes and Everything Burritos, which Finn, Mordecai, Rigby, Beast Boy, Richard, and Amethyst really love. He can also play the viola really well. And even though he's the oldest, he isn't as mature as Finn or Mordecai.


Mordecai is a 25-year-old 6-foot-tall blue-jay from Regular Show who is Rigby's best friend and the gardener at the CN YMCA. He is the most mature of the 4 main characters, normally correcting Rigby, Finn, and Jake of their immature behavior. Especially Rigby. Mordecai has a deep love interest for Princess Bubblegum, but he doesn't have the heart to tell her how he feels.


Rigby is a 23-and-a-half-year-old brown raccoon from Regular Show who is Mordecai's best friend and a janitor at the CN YMCA. He is the least mature of the 4 main characters, rarely seen doing anything for himself and depends on Mordecai to do nearly everything for him because he's lazy. He seems to be the most in tune with his animal instincts out of the 3 main animal characters as he runs on all fours to get somewhere in a hurry and digs in trash-cans to find extra food, much to a lot of people's general disgust. He also does a lot of things without thinking first.


Princess Bubblegum

Princess Bubblegum is Mordecai's love interest and later girlfriend. She is a 20-year-old candy person made of pink bubblegum (Hence her name.) and ruler of the Candy Kingdom. She often comes to the CN YMCA to take a break from her royal duties. It is hinted multiple times that she has the same feelings for Mordecai as he does for her. She is a science fanatic and often does experiments in her portable science lab.

Ice King

The Ice King is Finn and Jake's close friend and former enemy. He is very eccentric and a little crazy. He wears a magic crown which gives him ice powers and lets him fly with his beard. He also has a pet penguin named Gunter. He has lived for centuries due to his crown also giving him immortality. He often comes to the CN YMCA to visit Finn and Jake. He has a crush on Princess Bubblegum and will do anything he can for her. Even to the point of kidnapping her. He also deeply hates Mordecai since he loves Princess Bubblegum too and tries to kill him any chance he gets. Finn, Jake, and Rigby like to mess with him.


Marceline is a half-demon who was dubbed "Vampire Queen" soon after getting bitten by an unknown vampire. She is very powerful and knows how to use her supernatural powers really well. She is 1000-something years old and knew the Ice King (Before he became the Ice King.) from the time she was a kid. She is a rock musician who plays a red axe-bass which also doubles as a weapon.

He is a hybrid between a human and a Crystal Gem who is still learning his powers. He always tries to help his friends any way he can, usually only to cause more trouble.
