-- DJ Lance Rock – A DJ who is the narrator and friend of the other characters and the series' host.
-- Muno – A friendly male red cyclops. He's the tallest, is somewhat clumsy and has a close bond with Foofa (though she also bonds with Brobee in the same way). He is also the band's guitarist. In the episodes "Family", "Circus", and "Baby", his family makes an appearance. His realm resembles the moon, another planet, or a desert and he has a pet horse. His catchphrase is "Razzle Dazzle".
-- Foofa – A female flower bubble character who's "pink and happy." She loves flowers, rainbows and unicorns and can play the tambourine. Her realm is a spring or summer meadow.
-- Brobee – A small, male green monster and the baby of the gabbas. He is the drummer for the Gabba band. He is the only "primary" character whose facial expression changes depending on the situation; his usual smile turning into a frown, and vice versa. He is often subjected to trying new foods. His realm is a vast autumn forest. It is mentioned that he is four years old.
-- Toodee – A blue female arctic cat-dragon who likes to have fun. She has a close bond with Plex and is the bassist for the Gabba band. She lives in a winter arctic realm, with icicles.
-- Plex – A male magic yellow robot and the oldest of the gabbas. He is portrayed as being smart and as the leader of Gabba Land. Plex usually teaches lessons to his friends and is a father figure to the gang.
