Mechanical Sparrow

I've charged my daughter with looking after 3 pairs of pets, there's a pair of Guinea Pigs, a pair of (?? forget...), and a pair of sparrows, and somehow she's fucked up and one of each pair dead....I'm furious, smack her hard across the face and then discover the surviving sparrow is engaged in a duel to the death with a small mechanical sparrow, a medieval tin automaton that's battling it with a sword, I look to my daughter and her face is swelling and I feel bad about hitting her...
