Rainylune is the personal brand of the American independent artist Rachel Reichenbach. The core product is IPSon the Frog, which portrays a rebellious and cute frog who "wants to break the rules, loves pranks, and wears funny disguises". The visual style is a flat and minimalist 2D illustration, with soft lines and pastel colors. The characters are chubby and have cute expressions, full of childlike charm and humor. The scenes are mostly daily small adventures, with a naturally relaxing and comforting atmosphere. The frog's "crimes" (such as stealing snacks and causing destruction)  have a contrastively cute element, which is suitable for young women and collectors of trendy toys.
