Jacob "Jake" P. Spidermonkey is the deuteragonist of My Gym Partner's a Monkey. next to his best friend and straight man, Adam Lyon. He is a stupid, disgusting, destructive, and often times hilarious spider monkey, who goes to Charles Darwin Middle School.

He is voiced by Tom Kenny.


In "Talking Teddy", a flashback showed that Jake had been born and raised in the Zoo Aquarium, where he currently resigns. Jake, as a developing baby was shown drinking milk, fed to him by a zookeeper's hand, wearing a puppet that looked like a mother monkey, for the purpose of simulating a proper monkey's life. It is unknown why they needed to do this, since Jake's biological mother and father have both always lived with him, but this constant nurturing from a puppet has led him to grow confused about the lifelessness of puppets. In that same episode, he assumed Teddy Truman, a ventriloquist dummy, manipulated by Windsor Gorilla, was a real person.

Jake grew up in the Spidermonkey Exhibit of the Zoo Aquarium, with his mother, father, and brother. In "Pants in Space", he mentioned having a sister, but she had moved out and gotten married, sometime, when Jake was still young and in either elementary school or the early days of 6th grade. Jake first introduced Adam to his home in "Meet the Spidermonkeys".

Jake's family is possibly the largest and most explored family of the group. The Spidermonkey Family, though generally consisting of Spidermonkeys, when extended to distant cousins and in laws, consists of multiple different species of monkeys, not just Spidermonkeys. A whole crowd of them was seen in "Where in the World Are Adam's Parents?", watching the Mad Cows football game and later the school play with Adam and Jake. and in "Oh, Henry!", Jake had a macaque relative named Oxanna from Cyberia, though their exact relationship is unknown. More information about Jake's parents are known than Adam's, since those two have actually been shown on screen at times and portrayed as recurring characters. Jake's father has always been condescending and unappreciative of Jake, in a seemingly oblivious way. In "Where in the World Are Adam's Parents?", Jake was shown to have some real daddy issues with this, as he rubbed ketchup on his face, assuming it was blood and calling out "Why won't you love me, daddy!?" These issues have never been resolved. His father was also shown treating his wife with the same kind of respect in other episodes. The only time he'd even given positive acclaim to anyone was Adam in "Where in the World Are Adam's Parents?"

Jake went to Charles Darwin Middle School for 6th and supposedly 7th grade. In 6th grade, he first met Adam Lyon, who quickly became his best friend. In "The Morning Zoo", it was shown in a flashback that their first interaction was Adam asking Jake if he knew the whereabouts of Mr. Hornbill's class, to which Jake replied to with ignorance. However, given the goofiness of the flashback, having the duo dressed up in 1970's esque attires, it's not entirely certain whether this was official or just a gag.


Jake is a short, orange monkey with poorly groomed fur. He wears a blue, sideways baseball cap and a red T-shirt. He also proudly never wears pants, exposing his big, naked, plump, hairless butt, which he loves more than anything.


Jake is often very possessive of Adam and hates not having him around regularly. Jake is emotional and goofy who takes to heart some of Adam's comments and actions, leading to some overly dramatic and exaggerated reactions. He can be lazy and selfish, but at the same time he is also fairly sensible. Just as well, Jake tends to display feminine tendencies quite often.


Adam Lyon

Jake is the closest friend to Adam, and he loves him so much, he's gained an obsession with him. In "Sick Day", he was emotionally distraught by going a single day without him and revealed to have a shrine to him in his locker. In "A Whole Zoo World", he was unwilling to accept the fact that he'd be without him for the entire summer, and tapes pictures of him to the inside of his sunglasses, so he could always see him. Despite his love for Adam, he is not show him the most respect or loyalty. 90% of Adam's problems are derived of Jake's recklessness and stupidity. For example, in "Basic Jake", he got Adam sent to detention all weekend for something he didn't do. In "Up All Night", Jake kept Adam awake all night, causing him to sleep through his date with Kerry. When the two are in danger, Jake puts himself before Adam and often times, doesn't even bother with trying to save him.

Windsor Gorilla

Jake is friends with Windsor, but is often dumbfounded by Windsor's intelligent dialogue. In "Gorilla My Dreams", Windsor went on a tangent about love and Jake said it was the longest stream of words he's ever listened to. In "Pants in Space", Jake and Windsor butt heads and went to war over which one of them was more worthy of a simian to go into outer space. In "Meet the Spidermonkeys", Jake had a strict, but unexplained opposal to Windsor ever being his gym partner.

Lupe Toucan

Jake and Lupe are friends. Lupe is the least annoyed of his friends, since she's almost never lashed out at him for his obnoxious and reckless activity. This is because Lupe has a crush on Jake that he is completely oblivious to.

Slips Python

Although Jake and Slips are friends, Jake is a bad influence on Slips, as it's revealed that Slips' stupid behavior and air headed character is actually fueled by the peer pressuring of Jake. In "The Ivy League", the absence of Jake allowed Slips to be his true self, which was actually a very tamed, intellectual scholarly student.

Ingrid Giraffe

Ingrid, like the other friends is annoyed with Jake's annoying behavior and constant jokes about his butt, but since she's so quiet and submissive, she rarely ever complains about it.

Principal Pixiefrog

Jake is the most notorious troublemaker on Principal Pixiefrog's radar, winning in just above Adam. Jake always gets himself in trouble with him, but shows no care or regret, no matter how severe the punishment may be.

Bull Sharkowski

Bull is one of the few students at CDMS, who Jake doesn't constantly torture, since he knows his limits around him. Jake is smart enough not to mess with Bull at the expense that he could easily get beaten up by him.

Henry Armadillo

Jake constantly takes advantage of Henry's bright and sunny attitude by forcing him to do things that others would normally not want to do. In "Disregarding Henry", he took advantage of Henry's horrible singing, so that he could mock him in public and become famous off of him, claiming himself to be his talent agent.

Mr. Spidermonkey

Jake desperately seeks approval from his father, but he never gets it. His dad seems to be stupidly oblivious to the fact that he shows no appreciation for his son and makes a bunch of offensive comments about him, having no idea what affect it has on him.
