Whimsical Rainbow Jellyfish Watercolor Design コーヒーマグカップ

A watercolor-style illustration of a large pink and blue jellyfish with long flowing tentacles against a soft pastel background. The jellyfish has a translucent pink bell-shaped umbrella and pale blue tentacles with subtle ripples and waves. Four rainbow-colored bubbles float in the background, each showing a gradient of pink, yellow, and blue colors with a glossy, soap-like appearance. The background features a gentle gradient from light turquoise to pale purple, with soft brushstroke textures creating a dreamy underwater atmosphere. The illustration has a delicate, ethereal quality with subtle watercolor bleeds and drips around the edges of the composition. The tentacles of the jellyfish create graceful curves and waves as they trail behind the main body, rendered in varying shades of blue with pink undertones.
