Frog Attacks Chipmunk

This morning I saw the chipmunk go to get a drink from the pond, and then the large frog lunged out of the water towards the chipmunk! Normally the frog always dives under the water when anything approaches, but since the frog and the chipmunk are the same size, maybe the frog was more aggressive. The chipmunk ran off, then came back swishing its tail from side to side. I didn't see whether it tried to drink again, but I wonder if it can't see the frog because it is the same color as the duckweed.
