Eating Ice is Hard..

Today I saw something shiny in the bottom of mum's water glass. I decided to eat it to find out what it was, but first I'd have to get it out of that tall glass with my feet. I touched the bottom and EUK it was WET so I shook my paw and got water all over mum's desk. I tried again, and this time I bumped the glass over and was able to scoop out the hard, shiny and wet object. I tried to eat it but it kept sliding across the desk and left a watery trail.. and suddenly it wasn't there anymore. What!

Where did it go?!
