Blurb: Sonic the Hedgehog and Ladybird join forced to bring you some fast, furious, frantic and fun-filled radical action!
Summary: Robotnik discovers potential oil underneath the Aquatic Ruins Zone and sets up multiple rigs to mine for it. Annoyed at this, Sonic puts up a fight for the Zone's peace. Eventually Sonic redesigns Robotniks machinery resulting in Robotnik striking water instead of oil. This story is fully illustrated in colour and takes place in the zones of Sonic 2. Info by Ota.

Sonic the Hedgehog Robotnik's Oil book with "radical fold out picture" that is hopefully not of Robotnik's oil. This is obviously playing off an older book and possibly movie "Laurenzo's Oil" which is quite possibly boring.

In England, Virgin Books and Martin Adams did a series of 4 short story books. They don't seem to have inter-connected plots and they are NOT in comic book/graphic novel format. Each one has the "Back cover summary" provided by DarkWingUK. Thanks to the fans!
