My baby cocoa puff was hit by a car and died 3 mos. ago. I found his litter mate and rescued her yesturday.?

I had raised that litter until they were 12 weeks and they were adopted out. She was foung and i rescued her just before she was going to be put down. I need help with a name. I want to honor cocoa puffs memory. My mom says powder puff and im thinking cocoa pebbles. Shes all black- any suggestions?
