It may sound like an easy game at first, but one look at these photos and you'll be left questioning everything you see and before you know it you're left asking yourself "is that a chihuahua or a muffin?".
This is in fact Karen Zack's intention as she posts these puzzling animal and food mashups on her twitter @teenybiscuit. Describing herself as a "media production workhorse," Karen clearly knows a thing or two about her trade as her photos have been going viral all over the internet, inspiring others to create genius pairings such as "Donald Trump or raw chicken?" and one of our favourites "Snoop Dogg or real dog?".
