PabloPablo, a blue penguin wearing blue bow tie and a blue and yellow propeller beanie, is the one who most often has the ideas. Due to his energy and impetuousness, he takes the lead in many situations, but often goes into a "panic attack" when he faces an obstacle, running around in circles and telling everyone not to panic until someone interrupts him to propose a solution with "Pablo... Pablo?... PABLO!", at which point he stops, turns to the character and calmly asks "Yeah?". The number of panic attacks decreased considerably after the first season.

TyroneA good-natured (and sometimes fearful) red-haired orange moose, he is Pablo's best friend, and almost his complete opposite in terms of personality. He is laid-back, cool-headed, and known for his ironic comments. At the end of every episode, he remarks, "That was an excellent (type) adventure, don't you think?" Despite not appearing to wear trousers (except on rare occasions, such as "Race Around the World"), Tyrone somehow manages to put his hands in his pockets.

UniquaA curious, self-confident and high-spirited pink creature with polka dots and overalls, she is almost always sweet and friendly, though her strong opinions and occasional stubbornness get in the way of her relationships. She is more of a tomboy unlike her friend Tasha, often imagines herself in roles requiring brains and fortitude (scientist, pirate captain, etc), and loves books (as seen in episodes such as "The Masked Retriever"). But she can be sometimes more "girly" than Tasha in a few episodes.
Uniqua is a unique creature that is unlike any other in the world, and Uniqua is also the name of her species. Creator Janice Burgess describes Uniqua as 'the child she wishes she was like as a child'. She has been called simply "Uniqua, the pink" in Knights Are Brave and Strong.

TashaA little yellow hippopotamus, in red shoes and an orange flowered dress. Of the five characters, she is the only one who wears shoes at all times. She looks like a sweet little girl, but underneath she's rational, skeptical, and likes to get her own way. Whenever frustrated, she will always say "Oh for goodness's sake!". Of the five, she tends to be the most serious, though Tasha can also be giggly, silly and full of fun.

AustinA fun-loving purple kangaroo who moved into the block recently during Season 1; this makes him a little shy on some occasions, as in the episode Castaways. He is also self-confident, and tries to help his friends whenever they need, sometimes in quirky ways. Says Bogush: "Austin's usually the one pulling up the rear. He's kind of a get-along guy."
Although rarely appearing in the spotlight, he does take the role of the lead character in some episodes.
