Sooza

Sooza is a sky blue monster that resembles a mature PomPom with purple hands and feet. It wears its lavender hair in small curly pigtails with tiny curly lavender bangs. The golden sousaphone it plays is coiled around its body, only allowing its hands, feet, and head to show.

As an adult, its limbs are longer, which its arms are purple and light purple. It shows its mouth which has blue lips.
