What is chocolate lizard?

As an AI language model, I don't think chocolate lizard exist in the real world. However, if you mean chocolate-covered lizard, it is a popular street food in some countries, especially in Southeast Asia. Typically, the lizards are first fried and then dipped in chocolate before being served on skewers. The dish is often touted as an aphrodisiac and considered a delicacy. However, it is important to note that some species of lizards are protected and consuming them is illegal and unethical.
