The image exhibits four cartoon-style characters resembling anthropomorphic rabbits, rendered in black and white. From left to right, the characters exhibit the following distinct elements1. First character This character has a simple oval body, with an elongated head featuring two upright ears that are linear and taper to a point upwards. The eyes are large, circular, and wide-set with a small, circular black pupil. The nose is also circular and centered on the face, with a simple curved line for the mouth beneath it. It holds a spherical object with alternating shaded and unshaded vertical stripes with its hands, which are simplistic with three fingers each. 2. Second character Smaller in comparison to the first, this character retains the basic oval-shaped body but with a shorter stature. The ears are shorter than the first but retain the tapered linear form. The eyes are large, oval, and contain wide pupils while showing different expressions, one eye appearing slightly squinted. This character has a simple curved mouth and no nose visible. Its arms are raised, each ending in a hand with three fingers.3. Third character Similar in scale and shape to the first character, this one features drooping ears rather than upright. The eyes here are oval and the furrows above suggest a worried or concerned expression. This character''s nose is also round, directly above a frowny, curved mouth. Its arms hang by its sides and its hands are structured the same as the other characters'' hands.4. Fourth character This character is identical in scale and postural design to the second character, featuring upright ears and an oval body. The eyes are wide and circular, and it displays a neutral expression with an open, rounded mouth. The nose is prominent and circular. It holds a striped spherical object similar to the one held by the first character. Its arms are slightly extended to its front.Each character is outlined in black with internal features such as the eyes, mouth, and held objects
