This is a popular video going around the internet these days.
Some water buffalos were walking around and got attacked by lions, who caught one of the babies. The lions proceed to start trying to eat the baby water buffalo, when out of nowhere an crocodile (or was it an alligator) pops out of the water and tries to steel the lions soon to be lunch. A short scuffle ensues and the lions emerge victorious.
In the meantime, the water buffalo seems to have gone off and rounded up their friends and come charging back to rescue their young friend.
Pretty entertaining viewing, enjoy.
