End of gecko

The sidewinder's favorite meal is the diving gecko. But geckos play hard-to-get.
So the sidewinder resorts to a very sneaky trick to catch his prey.
First, he buries himself in the sand until he is quite invisible.
Then his tail comes up and pretends to be a blade of grass.
Now, geckos don't eat grass, but ants do. And geckos eat ants.
At this point, things happen rather quickly.
Ant goes for tail, gecko goes for ant...
End of gecko.
