Art style: Классическая 2D анимация.
Full-length view, the entire figure visible from head to feet, standing upright and centered — a small male beaver kit, the middle of three sleepy siblings. Rounded chubby body with soft warm-brown fur, a broad flat paddle-shaped tail, a wide friendly muzzle, two prominent little front teeth, small round ears and a dark button nose. His eyes are squinted almost shut, half-awake, adjusting to the light, with a slightly grumpy drowsy expression. He wears a cozy sky-blue two-piece pajama set with long sleeves and pants, softly wrinkled from sleep, a small buttoned collar. His short-fingered paws hang relaxed at his sides. He stands on bare padded feet on the wooden floor of a warm hallway, morning light spilling in from the side, a doorway and coat pegs softly blurred behind him.
