Rspec double returning NoMethodError

Not sure if my syntax is right, it doesn't seem to recognise the stub I've passed to my double.

class Robot
  def boogie friend
    friend.dances
  end
end

Test:

describe Robot do

let(:robo_friend){double(:friend, {dances: true})}

  it "should have a friend dance too" do
    expect(subject.boogie :robo_friend).to be true
  end

end

And the error:

Robot should have a friend dance too
 Failure/Error: expect(subject.boogie :robo_friend).to be true
 NoMethodError:
   undefined method `dances' for :robo_friend:Symbol
 # ./lib/robot.rb:3:in `boogie'
 # ./spec/robot_spec.rb:8:in `block (2 levels) in <top (required)>'

Can anyone see what I'm doing wrong?

This will work, you need to pass the object and not a symbol.

describe Robot do
  let(:robo_friend) { double("Friend", dances: true) }

  it "should have a friend dance too" do
    expect(subject.boogie(robo_friend).to eq(true)
  end
end
