Jiminy Cricket serves as the conscience for a wooden puppet brought to life by the Blue Fairy in Walt Disney's Pinocchio in 1940. Since his debut Jiminy has become an iconic Disney character. He's hosted many Disney cartoons and tv specials, he appears in the Kingdom Hearts video game series, and can be found at Disney Parks world wide.
I love that he's also a character in the ABC show Once Upon a Time! Raphael Sbarge plays Jiminy Cricket and Archie Hopper, the human version who lives in Storybrooke, Maine. They created a whole backstory for Jiminy. He was the son of two swindlers who wanted to escape the life he had. He wished on a star and the Blue Fairy asked him what he'd rather be. He chose to become cricket, who who he always thought of as being free.
