A yellow cartoon character is sleeping in bed

A cartoon character with yellow skin is lying on the bed sound asleep, eyes tightly closed, with a brown mouth slightly open. The character's head and the blanket covering its body are outlined in simple black lines, presenting a minimalist flat animation style. The background is a pure bright blue with no other decorations or environmental details. The composition is centered, with the character positioned slightly above the center and ample negative space surrounding it. The overall color contrast is sharp, with even and flat lighting, no distinct shadows, creating a tranquil, minimalist, and slightly lazy visual atmosphere.
