Jenny Lana's cake is not only realistic, but fairly easy to make. The Sarlacc itself is made from a split chocolate-covered stawberry (the mouth), chocolate-gummy worms (the tentacles) and almonds (the teeth). Watch a video of her step-by-step instructions at the link. Don't worry, you won't need a thousand years to digest it.
