Create one vertical 9:16 image of the couple in as original characters in Adventure Time. Closely match the show's actual 2D visual language: thin clean black outlines, flat bright colors, simple rounded silhouettes, dot eyes, tiny expressive mouths, flexible noodle-like limbs, and whimsical painted scenery. Preserve recognizable hairstyles, hair colors, distinctive personal features, apparent ages, gender presentation, and relative height within this simplified design. Do not turn them into Finn or Fionna or cover their defining hairstyles with identical hats. They hold hands on a grassy hill in the Land of Ooo, with the Candy Kingdom in the distance, ready to take a playful step together. Affectionate, adventurous mood. No 3D rendering, panels, text, logos, or watermark.
