Players divide up into teams.
The game works best if there are at least 2 or 3 people on each team. Players lie down on their stomachs, with their elbows bent in front of them. Using only their arms to propel them, they crawl to the turn around line and back, all the while barking like a walrus. When they get to the finish line, they tag the next player in line. The first team to have all it's players done wins.
