Take just one single look at their mouths. :3

Super Sonico's :3 minions. :3 combos so purrfect.

Just look at that face with the delightful colonthree expression. :3

Nyarcueid ("Neko Arc"), the cat-version of Arcueid Brunestud has a very nice :3 face as well as a smiley!

the :3 gets sweeter and sweeter

The colonthree is present, especially in the smiley :NorminBlue: :3

The colonthree mouth is omnipresent in this cartoony representation of a cat. :3

Garfield obviously has a wide colonthree-mouth. :3

Some of the characters and monsters are :3. The game over all is designed well and the music is fluffy.

It has :ping3: in it which is a neat colonthree-smiley based on Shobon from Japan. （´・ω・｀）
