>>12746812It's not, because that smiley face in the logo is ugly. Vanillite's face looks nothing like it and it's cute. and Vanillite has a body to make it's head look big, and has stubby arms.
Jigglypuff is also cute just because of it's face and body proportions. So is Jumpluff, Litwick, Budew, Rotom, Oddish, Wooper, Sentret and basically anything that isn't humanoid or too similar to a real life animal.

>>12746711 explained, what makes something cute is not what it is, but it's proportions and how many "cute" features it has. A hammer can be cute without even having a face, so a smiley ice cream cone can be adorable.
Pic related, anything is cute if drawn with the right proportions.
Now please do explain what *is* cute to you, then.
