Adorable: Cute baby wallaby sucks on "thumb"

(CBS) - There may not be a "missing link" between humans and marsupials, but if there were this video would definitely help to prove it. In it an adorable baby wallaby is shown stooping down to suck on the equivalent of his "thumb". Awwwwww...!!

The obvious connection between the wallaby infant and a human baby in terms of this behavior is undeniably ADORABLE! There seems to be a definite trend today of cute animal antics - enough for me to officially declare it "Animals Gone Viral Day"!
