Lumpy was more of a nemesis than a friend, but I think he'd haunt me if I didn't include him here. Lumpy is made entirely out of mashed potatoes, with the exception of his pea eyes and dark gravy tongue.
Lumpy is the starchy vegetable treat that chased me, horrifically, in my fevered nightmares. I'm sure if he had ever caught me, he'd have eaten me alive with steak and carrots.
Mr. Cheese was actually my little brother's alter-ego. The only difference between Mr. Cheese and my bro was a voice like Froggy from Little Rascals. I imagine this is what Mr. Cheese would have looked like if he hadn't been trapped in a ten year old boy's body.
The Dragicorn is the magical half dragon/half unicorn that I used to imagine myself being friends with when I was playing outside as a child. I'm not sure what transpired to cause a dragon and a unicorn to fall in love, but their child sure was cool.
I created Freddy Frog as a comic strip in fourth grade, and drawing literally hundreds of comics about him and his adventures got me through some tough times, including moving to a new town in the middle of the school year. I debated posting him here, as he's very much still alive in my mind and I plan to do something with him eventually, but he is probably the best imaginary friend I ever had. There wasn't a notebook or textbook or coloring book cover or post-it that was safe from a Freddy doodle. He was a constant companion, and, trust me, he had some totally rad skills. (To quote my younger self.)
