Will the robotic squirrel gets its head bitten off literally?
In the first clip, the robotic squirrel is remotely controlled to tail flag. The hidden rattlesnake shows no response. In the second clip, the rattlesnake is hiding in ambush position at a different location. In response to the robotic squirrel approach with no tail flagging, the snake launches a venomous predatory attack at its head.
