Razl and Dazzle

Tunas are living cartoons made of ichor.
Ichor is a black, viscous liquid from which all thuns were created. Ichor itself is poisonous to humans, so it was stored in capsules; thuns are immune to it, as it's what they're made of. The ichor machines are large capsules, about two meters tall, and to fill them, you turn a red valve, and the ichor will flow through the pipes.
Maines are the main characters. Each event toon has its own main (Christmas toons have Bobet, Easter toons have Bessie, and Halloween toons have Gordy).
The name of the children's show from Where All the Tunes Appeared is "The World of Dandy" or "Gardeview".
Children often come to Gardeview, because this building is often used not only as an animation studio, but also as an entertainment center for children, and maybe even as a kindergarten. In general, children often run around Gardeview with their favorite cartoon characters.

Razl is a white comedy mask, constantly smiling and sporting grayish blush. Dazzle, on the other hand, is a black drama mask with white tear stains. Razl and Dazzle share a single body, as they are Siamese twins, their heads connected by two red ribbons at the neck. Razl and Dazzle's bodies are half black and half white, and they wear a black poncho or a Harlequin-like outfit in black, red, and white, although Razl and Dazzle prefer acrobatics.

Razl is also the complete opposite of Dazzle. Razl is a comedic foil; he's very loud and loves the spotlight, but he understands that his brother needs peace, though he respects him sometimes. Razl is bad at filling the ichor machines because he's often distracted and doesn't enjoy the time it takes to turn the valve, so filling the machines falls to Dazzle.

Dazzle is the complete opposite of his brother, Razl. Dazzle isn't very outgoing and is a bit of a whiner, as he's a mask for drama. Unlike his brother, Dazzle doesn't like running, as he gets tired quickly and is generally slow, so the running usually falls to Razl.
