A San Diego squirrel proved that it's never a bad idea to root for the underdog after it engaged in a tense brawl with a lethal competitor.

The San Diego National Wildlife Refuges shared the tense video depicting a ground squirrel tossing wood chips and asserting its dominance against a southern Pacific rattlesnake.

As the rattlesnake hissed and prepared to pounce, the squirrel pushed woodchips in its face and stood strong in the face of danger.

The squirrel wasn't rattled, as it flicked its tail at the snake, jumped around to confuse its foe, and kicked up woodchips to throw in its face.

The SDNWR snapped the footage and shared it online to their followers, revealing that the bitter duel lasted a whole eight minutes.
