Cartoon characters are in a room with a green light

Create an anime-style digital artwork. The composition should feature two contrasting characters: the character on the left is a small green aura with facial expressions. The other is a very friendly robot. The setting should be minimalist, suggesting a light-hearted and whimsical atmosphere with elements like floating bubbles or particles to signify dynamic interaction. The style should be crisp and expressive, with sharp outlines and a playful color scheme that highlights the imaginative and vibrant nature of the scene.
