Sarcastic Slab is a Slab that appears in the mission The Once and Future Slab. He registers as a hostile target, but will not attack and does not present any threat whatsoever. Instead, he slowly claps and sarcastically offers praise for passing the Slab initiation quoting the following: "Yeah. GREAT job. We're all sooooo proud that you managed to kill off our friends and brothers. You're just sooo cool. This is totally not sarcasm". Hitting him will make him move slightly faster. Killing him will elicit a comment from Brick: "Wow, you ARE a true Slab."
