Stylized 3D character reference sheet, Pixar style, plain white
background. A comical gross-but-cute PLAQUE BACTERIA used as a soft-
menacing creeping SHADOW of neglect: pale-yellow sticky blob with
buck teeth, here rendered more as a shadowy looming threat than a
clown, quietly menacing but kid-safe (NOT scary-realistic).
SHOW 4 ANGLES PLUS expressions: soft-menacing, looming, recoiling,
defeated. Consistent design. No text.
