- This achievement used to be a task prior to the release of the Achievements System on 18 April 2017.
- The name of this achievement is likely a reference to Marvin the Martian of Looney Tunes fame, who would often ask "Where's the Earth-shattering kaboom?" when Bugs Bunny would snuff out the fuse on his "Illudium Q-36 Explosive Space Modulator" he was trying to blow up the Earth with.
