An animated TV series about seven anthropomorphic bears lived in medieval time at once populous big tree called Gummi Glen. The great gummies are refugees and looking for their ancient city with the help of their human friends and the Great Book of Gummi to resurrect the city and reunite all other bears scattered around the world. The bears are also the secret defenders of the Dunwyn Kingdom against former knight Duke Sigmund Igthorn and his created ogres army, but when the bears consume their secret Gummibeary juice give ability to bounce and also give human to temporarily become superhumans.The seven gummies living Gummi Glen:
- Gruffi - Gruffi also can be viewed as the de facto leader of the Gummi Bears. A no-nonsense, perfectionist and conservative every-job-Gummi.
- Zummi - The colony's "keeper of Gummi wisdom" turned magician with unreliable skill. Frequently forgets important things, including spells, at the worst possible moment and does spoonerisms when stressed.
- Grammi - The matriach of the Gummi clan, she cooks and cleans and prepares the gummiberry juice. Her cookings - which sometimes are purely experimental - are not always appreciated by the others.
- Tummi - the gluttonous teenaged Gummi who is seemingly slow in thinking and action, but is as courageous as the rest. He has a sweet tooth and is a talented planter and loves building model boats.
- Sunni - "token adolescent" of the bunch who often rebels against the clan but learns her lessons eventually. She is quite fond of rather 'radical' fashions. Her dream is to one day be a princess. Even though Sunni and Calla are best friends, Sunni occasionally displays mild jealously of Calla because she is a princess.
- Cubbi - the youngest Gummi. An aspiring knight, he is always looking for adventure, and often finds it. Because of his youth, he is often not taken seriously by the others, which is just as frequently a huge mistake. When fighting crime at Dunwyn, he uses the masked identity of the Crimson Avenger.
- Gusto (Augustus) - the artistic Gummi and an individualist, he lives away from Gummi Glen with his toucan friend, Artie Deco. Gusto is an artist who is very creative with mercurial moods depending on how well his (sometimes unsophisticated) work is going or being appreciated. He sometimes goes to Gummi Glen to visit the rest of the Gummis.
- Cavin - Cavin is the squire of Sir Tuxford, the highest knight in King Gregor's court. Cavin befriends the Gummi Bears in the first episode and shares the same ambition as Cubbi - to become a knight. Cavin also had the medallion, given to him by his grandfather, that opened The Great Book of Gummi, the source of all Gummi Bear wisdom. The young squire also has a secret crush on Princess Calla.
- Princess Calla - Princess Calla is the daughter of King Gregor, ruler of Dunwyn. She is an adventurous character and she often drags the dumbstruck Cavin (who she is overly fond of) into story situations. Calla also befriended the Gummi Bears and is close friends with Sunni. She hates the pomp and circumstance that comes with being royalty while wishing to be more involved in the governance and defense of the realm. Consequently, she tends to be somewhat rebellious at times, often spurning her father's admonishment that "a princess must set an example for her people."
- King Gregor - King Gregor is the ruler of Dunwyn. He is a brave figure and protects his people from villains like Duke Igthorn with the help of Sir Tuxford and his knights. Gregor is unaware of the Gummi Bears' existence or involvement in saving his kingdom many times. His pride and joy is his daughter, Calla, which later included considerable respect of her previously hidden fighting prowess.
