Made in a small studio, Fantome in France, it was one of the earliest computer-animated series alongside VeggieTales and ReBoot.

Joyces (Verigreens) are colorful, cheerful insects and offshoots of the Yuk/Krud civilization who broke away from their dark cousins upon the arrival of the Great Prism which nourished the site where it landed, resulting in the creation of Flower City.

Exposure to brightly colored substances (pollen, juices from mushrooms) causes them to enter states of uninhibited laughter.

At one point, a Prism shaped meteor hit the planet and nourished the site on which it landed with color and energy, resulting in a flower-filled paradise.

The Yuks/Kruds who chose to stick to their original lives continued mining for coal till they gradually exhausted their supplies.

The animosity between the two insect civilizations began when a violent Yuk/Krud known as King Bakrako/Katheter the First came up with the solution of using the Joyce's/Verigreen's flower stalks as substitute fuel sources.
