It works on the moon, it walks a bit like those Star Wars walkers in the snow. Actually my Dad helped me make this, I was watching kids TV and I stayed home from kinder because I have a cough.I have lots of tissues, and Mum does give me that strawberry medicine which I like better than that cherry medicine. And she did let me have those brick lollies (butter menthol) and sometimes rubs that sniffy cream (vicks) on my body.
