Who are these creatures?

So, I was looking for something on my computer the other day, and I came across some pictures of some creatures I could no longer identify...

These adorable creatures don't look anything like the ones I now have living in my house. :) Those were during the sweet, cuddly, "I like mom" days....as opposed to the rolling of the eyes, "Mom makes me eat my vegetables and do my homework so she must be no fun" days....in our house, Dad is definitely the "cooler", Rock-Star parent most of the time...
