The Swish Swish songstress shared a video alongside her sister, Angela, as she introduced a new song that she had called "Moose Moose Alpaca" that had been designed as a campfire song for teenagers. The song featured a wide variety of moves each corresponding to a different word, including the titular 'moose' and 'alpaca', but also including 'pufferfish', 'flamingo' and 'ninja'.
