Wide-Eye is a British 2003–04 animated children's television series set in fictional Natterjack Forest. The series consists of a series of ten-minute episodes and is about a wise, old owl who lives in a tall tree with his young son, "Little Hoot", and his energetic female sidekick, "Flea".

• Wide Eye the Owl (voiced by Anton Rodgers) is the title character who lives in the tallest tree in the forest with his young son. Little Hoot and his sidekick, Flea. Wide Eye is fatherly, gentle and reliable. He mostly watches over all the animals to make sure they are all safe and happy and speaks in a deep voice.
• Little Hoot – (voiced by Maria Darling) – Wide Eye's son. He is brave and strong, speaks in a high-pitched voice, is full of adventure and imagination, can see in the dark and is always eager to learn, although like many children, he is sometimes daunted by new challenges.
• Flea – (voiced by Jane Horrocks) is Little Hoot's childish English-accented female sidekick and best friend. Flea can jump the highest and she is always ready to join in with Little Hoot's adventures.
• The Natterjack Toads (Nat voiced by Maria Darling, Flo voiced by Jane Horrocks and Jack voiced by Jimmy Hibbert) are three green and orange toadlets who live and play at Natterjack Pond.
• Mother Natterjack – (voiced by Jane Horrocks) is a female orange toad who is mother of the Natterjack Toads.
• Great Grandma Toad (voiced by Anton Rodgers) is another female orange toad who is grandmother of the Natterjack Toads. She wears purple glasses and often cooks healthy food for all the natterjack toads to share.
• Father Natterjack (voiced by Anton Rodgers) is a male green toad who is father of the Natterjack Toads.
• 99 the Centipede – (voiced by Jimmy Hibbert) – Lives alone in a burrow dug deep into Natterjack Forest floor. Easily distracted, he tries his best to count and match his many pairs of coloured boots, but he keeps losing count, and is forced to start over and over again.
• Conchita the Chinchilla (voiced by Maria Darling) is the friendly blue and white Chilean-accented kindhearted soul of the forest with good eyesight. Conchita lives under the roots of a tree. She dances and sings as well as cooking South American food for all the forest animals to share. She can often be seen wearing exotic Chilean clothing.
• Rangatang the Orangutan – (voiced by Jimmy Hibbert) – Lives in a treehouse. He often plays jokes on the other forest animals as well as bringing fun and games to the forest and running a cornershop.
• Hetty Hornet (voiced by Maria Darling) – Lives in a beehive and likes the forest to be clean and tidy. She always tries to keep the other forest animals on their toes by handing out useful little tasks to keep them busy.
• The Fireflies – Several nocturnal fireflies who appear at night in Natterjack Forest. The fireflies themselves only make buzzing sounds instead of saying words.
• Wily Komodo (voiced by Jimmy Hibbert) is Baby Komodo's dad who appears in almost every episode in the series. He almost always causes mischief in Natterjack Forest. He lives in a rocky, roofless den with his young son, Baby Komodo, and because time is never on his side, he causes nothing but mayhem wherever he goes.
• Baby Komodo (voiced by Jane Horrocks) is Wily Komodo's young son who is fond of swimming. Although he desperately wants to be as silly as his dad, Wily Komodo, as well as be friends with the other natterjack forest animals, his main skills are dribbling, running, and even din-making.
• Batwing the Bat (voiced by Maria Darling) is Wily Komodo's spy. She sleeps upside down in her rocky cave on the outskirts of the forest and can fly unaided, even at night.

• The Moon is a real, faceless, silent moon which appears every night of the year in Natterjack Forest. The moon is not always seen in the sky, but its only role is to brighten up the darkness in the forest between dusk and dawn every day of the year.
• The Sun is a real, silent, faceless, dazzling, hot star which appears during various episodes, including Snapdragon Monster and The Forest Regatta. The sun generally shines in the sky above Natterjack Forest between Dawn and Dusk every day of the year, but, although it is not always seen in the sky and can hurt the forest animals' eyes and make them go blind, it is by far the most important source of energy for life in the forest.
