Short-ish Adventure

Taking the safe route (coward) you swimmeth through the river. As you swimmy swim, you look up, at what appears to be yourself hurdling through the air at a tremendous velocity. You barely have time to react before your alternate self flies past. Amidst the chaos, an alligator drags you by the feet and pulls you under the water. He looks scary at first, but is actually pretty nice, and sits you down at his table. You suddenly realize that you desperately need air to breathe. What the heck do you do?
