An annoying white girl who plays volleyball. She catches feelings very fast and her fetish is butts. She has really weird glasses and teeth. She looks like the sloth from ice age. She also moves around a lot

Get the siennamug. Sienna the shy girl on the block, most of the time you'll see her smiling but when shes around people that piss her off she get shitty and walks away she only wants friends to support her but know one understands her. if you meet this girl shes probably sad so leave her alone and walk away. Anyone who disrupts her when shes by her self should back away slowly or you will be flooded in sadness.
