Flat vector mascot character illustration of a friendly anthropomorphized open hardcover book. The book is the body: an open book standing upright on two short rounded legs, with two stubby arms. Big expressive cartoon eyes and a warm welcoming smile on the open pages. One arm raised holding a small wooden teacher's pointer, gesturing as if explaining a lesson. Wearing small round glasses to signal "smart teacher." Floating educational symbols around it (letters A B C and numbers 1 2 3, a lightbulb). Style: bold flat design, thick rounded chunky shapes, minimal internal detail, high contrast, single hero color palette (warm teal body with orange accents), soft subtle gradient shading, clean geometric silhouette that stays readable at tiny sizes. Cheerful, approachable, gamified learning-app aesthetic. Centered composition, front-facing, full body, generous negative space. Transparent background. Square 1:1. High resolution. Vector-clean edges.

The image shows a cartoon character holding a book with a light bulb above it and the words "1b2c" written on it. The character is wearing glasses and has a cheerful expression on their face. The book they are holding is open and the light bulb is shining brightly, illuminating the page.
