An untrustworthy character with a sly expression, holding a twisted, dark-colored idea in their hands. The character's appearance should convey deviousness and instability, with a mischievous glint in their eye. The idea they hold appears spoiled and rotten, symbolizing the concept of a 'bad idea'. The background should be dimly lit to enhance the ominous feeling of the scene. The style is vibrant children's animation, with exaggerated facial expressions and gestures to emphasize the negative nature of the '餿主意'.
