Gigi

Gigi is quite laid-back, sociable, and friendly, but can be chaotic and unpredictable with other Toons. Gigi is also a thief and doesn't like keeping promises. Gigi's best friends are Coney (a ghost), Flutter (a butterfly), and Poppy (a bubble).

Gigi is a red Gachapon with red limbs, but her legs are a darker shade of red down to her feet, which are the same color as the rest of her body. The top half of her head is transparent and can open. She wears a light blue sweater with a yellow star in the middle. She also has long sleeves that extend beyond her hands, completely covering them.

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.
