Playful Kangaroo in a Castle Courtyard

Adorable cartoon kangaroo in a sunlit castle courtyard. The kangaroo stands upright on two legs with a big round head, oversized eyes and a joyful smile. It wears a tiny golden crown and a bright red cape that flutters as it hops. The courtyard features grey stone walls with creeping ivy, a grand arched doorway, colorful banners, a stone fountain, and potted flowers along the edge of a grassy border. The ground is cobblestone with a few scattered leaves. The scene uses bold black outlines, flat saturated colors, and gentle shading in a modern children's cartoon style. Composition is slightly from above to create depth, with a cheerful adventurous mood and a clean vector like illustration suitable for kids.
