It was one late evening while I was sleeping, when my walkie-talkie suddenly stared to ring..   

Izzy hello?

I answered: 

I heard a strange voice:

Hi Izzy, my name is Greenie.

Can you please open your bedroom window? 

To my surprise, there was a space-ship and three aliens in our garden.

One of them (the little one) was also holding a giant glass of coke-a-cola.

"We are from Mars. Our last ice-cap has melted, so we have ran out off ice for our coke-a-cola. Can you help us find some ice?"
