Garlic eaten, but by who?

So I pulled some autumn planted garlic a couple of weeks ago and popped them in to the log store as a temporary measure to start drying as i was in a rush and thought I'd go back and move them to my usual place in the garage when i had a minute. Suffice to say I forgot. Anyway, I've just got to them and the majority are fine but something has been at some, see the picture. 
Any idea which of our little friends would eat garlic bulbs?
