Hello, everybody!

Kaeloo the frog is the series' protagonist, who the show is named after. She is the guardian of Smileyland, and is usually the one to suggest the games the characters play.


Kaeloo is a small frog. She has a green body and her belly and the lower half of her face are yellow. She has red eyes, two red spirals on her cheeks and bright white teeth. It is often implied that Kaeloo may be slightly overweight.

As Bad Kaeloo, she is twice her normal height. She is large and muscular, with visible veins. Bad Kaeloo has several yellow spots on her body and the red spirals are not present on her cheeks. She has very poor oral hygiene. Her tongue is blue and her teeth are not properly aligned. Her right eye has a yellow scar running through it.

In "Let's Play Quantum Mechanics", Kaeloo briefly appears in the form of a human. Her human form is Caucasian. She has green shoulder-length hair with bangs in the front and red eyes with thick eyelashes. She wears a yellow tee-shirt, denim overall shorts, and brown boots.


Kaeloo is a sweet and imaginative but dangerously emotionally unstable little frog who's always looking for games to play with her "buddies". She is very kind and forgiving, and she still sees Mr. Cat as a friend and tries her best to make him feel happy and welcome despite his cruel and sadistic nature. She is also usually the one to stand up for Quack Quack when Mr. Cat is tormenting him, and she is fiercely protective of the flowers of Smileyland. Kaeloo loves all things "cute" or "beautiful". She also enjoys things that most people would describe as "mushy", such as handwritten love letters, fairy tales, and soap operas. Kaeloo is a well-organized person who respects tradition, and freaks out when things are disorganized or when rules are broken. Kaeloo is extremely naïve and childlike; examples of this include her thinking her missing keys are "playing hide-and-seek", and her interpreting one of Mr. Cat's sexual-innuendo-laden pick-up lines in a literal manner and misunderstanding him.

Kaeloo fantasizes about a fairytale happy ending

"Hello Mrs. Flower!"

Kaeloo tries her best to remain calm, but with enough provocation, she enters an intense rage which transforms her into a hulking toad named Bad Kaeloo. As Bad Kaeloo, she is very mean at times and seems to enjoy abusing Mr. Cat, although upon returning to her "normal" form she will apologize for her actions. Nevertheless, Bad Kaeloo also shown to genuinely care about her friends. This includes Mr. Cat, as she has been seen laughing with, protecting, and even kissing him.

Kaeloo has also shown a less pleasant side of her personality, like in "Let's Play Courtroom Drama" when she emotionally manipulates Mr. Cat, or in "Let's Play Curse of the Pharaoh" where she pretends not to notice that Stumpy is drowning in quicksand. Despite usually being vehemently opposed to cheating, Kaeloo will occasionally cheat to win, as shown in "Let's Play Golf" and "Let's Play Baseball". Although Kaeloo is forgiving, when pushed past a certain point, she will not hesitate to get revenge on the person who made her angry, like in "Let's Play Top Models" when she enlists Mr. Cat's help to get revenge on Pretty for body-shaming her. Also, due to the fact that she is the one who comes up with most of the games, she believes that she is entitled to be bossy while playing and gets angry whenever someone questions the rules. Kaeloo occasionally acts selfish as well; in "Let's Play cupid.com", Mr. Cat stops hurting Quack Quack to annoy her and while Quack Quack is happy about the change, Kaeloo wishes that Mr. Cat would beat him up just so she could get attention from Mr. Cat. This suggests that her protective nature to Quack Quack is, at least in part, a façade to make herself look good.

Despite this, Kaeloo remains a largely non-confrontational person and tends to address many conflicts in a subtle manner. In "Let's Play Top Models", instead of directly confronting Stumpy about being too noisy, she tells Quack Quack in a loud voice that she appreciates how quiet he is in comparison to Stumpy, and in instances where she sees someone else flirting with Mr. Cat, her crush, she finds an excuse to remove them from the scene instead of directly expressing that she wants them to leave.

It has often been hinted at that Kaeloo has terribly low self-esteem. The most prominent example of this is "Let's Play cupid.com". Pretty tries to use a love potion on Mr. Cat but ends up making him fall in love with a soda can, leading him to ignore everyone around him; when Kaeloo realizes that this also means he won't abuse Quack Quack and therefore she doesn't have to protect Quack Quack anymore, she cries because she feels "useless". In "Let's Play All Alone", Kaeloo falls into a depressive state because her friends are gone for the day and hadn't informed her in advance; Mr. Cat, who is out partying with some other friends, is talking about Kaeloo to said friends at the same time she's worrying about being abandoned, proving that her fears are unfounded. "Let's Play Beach Volleyball" and "Let's Play Forest of Spankings" also suggest that she has body image issues.

Kaeloo is often quite possessive of her friends. In "Let's Play Sleep Train" and "Let's Play Imaginary Friends", she is upset by the idea of her friends having friends other than her. The latter is a particularly egregious case as the friends in question were imaginary friends. This possessiveness especially applies to Mr. Cat, as she dislikes seeing him with other girls.


Kaeloo has the power to transform into Bad Kaeloo, a muscular toad. Whether or not Kaeloo can voluntarily transform without being angered depends on the episode. Bad Kaeloo has impressive athletic abilities, such as stopping a car with her bare hands, throwing Mr. Cat into the air at a speed of 88mph, and holding off a meteor.

"I talk too much?!"

Starting from the show's third season, Kaeloo has been able to transform partially, or to transform a specific body part while the others remain intact.

Kaeloo's "half-transformation"

Kaeloo has a lisp, which can cause misunderstandings between her and the other characters, especially in the French dub since she pronounces words in such a way that they sound like different words altogether. In early episodes, the other characters, especially Mr. Cat, used to make fun of her for it. As Bad Kaeloo, however, she can speak without a lisp.

It was heavily hinted at in "Let's Play Spies" that Bad Kaeloo is the original form, and Kaeloo is another form she takes on to be able to make friends. According to Dr. Jean-Guillaume, Bad Kaeloo is Kaeloo's unconscious self expressing itself.

Kaeloo is a master of martial arts, even in her "normal" form. She can also use her tongue to snatch things when necessary.

Kaeloo's intelligence varies between episodes, from being somewhat smart to being a complete idiot.

Role in the show

Kaeloo is the protagonist of the show. She is normally the one to suggest playing the games the buddies play. She is the guardian of Smileyland. Most episodes revolve around Kaeloo's superpower of being able to transform into Bad Kaeloo. Whenever something goes wrong in Smileyland, Kaeloo attempts to fix it, often with help from her friends.


As the protagonist of the show, she appears in all episodes.


Kaeloo's gender has always been unclear for fans of the show. The Italian fan dub and the Hindi dub labeled her as male, however, she has been referred to as a female in many episodes of the show. In the French dub, everybody refers to her as "elle" ("she"), and uses female adjectives when talking about her. There was also a mistake with the dubbing in the English dub when Kaeloo was referred to as a "he" for the first ten episodes. This was soon changed however, everyone referring to her as a "she". On the show, she has shown attraction to both male and female characters. The show's official Facebook page has confirmed that being a frog, she is able to change sexes.[1]


Kaeloo tries her best to maintain a decent relationship with everyone in Smileyland, no matter how antagonistic they may be towards her. She is particularly close with Stumpy, Quack Quack, and Mr. Cat, the latter of whom she has a crush on and is the closest with. Kaeloo is very possessive of her friends and dislikes it when they talk about their other friends to her, even if the friends in question happen to be imaginary friends. Kaeloo often irritates the other characters and causes conflict, usually without meaning to. This has led to certain episodes being centered around Kaeloo losing all her friends, with the exception of Mr. Cat, and the latter helping her patch things up with the others.
