Cute Cartoon Koala with Steaming Thermos on Tree Tシャツ

An adorable chibi-style koala character with grey fur, large fluffy ears, and pink rosy cheeks. The koala is sitting upright on a brown wooden tree stump which has a small green leaf sprout on the side. It holds a red and blue thermos flask with both paws, from which a puff of white steam is rising. The background is a plain, solid light grey color.
