Mouthlessnesssssss

There was a comment I heard once from a good friend in Japan and coincidentally from another person in Finland, that childhood cartoon characters such as Sanrio's Hello Kitty
or the Moomin were well-liked and persistent because of the lack of mouths. Hmmm... could be something sociological or goes with the old saying...children should be seen not heard :-)
Kind of contrasting with the flamboyant and "big-mouthed" Barney... and of course all-mouth Pacman. Heeheehee (^_^)
