Crazy Gadget is Sonic the Hedgehog's penultimate level in Sonic Adventure 2, in the Hero Story. The stage takes place in outer space on the Space Colony ARK.


Sonic arrived in the main computer room aboard the Space Colony ARK to fulfill his part of the mission of stopping Eggman's plan to dominate the world. Over Sonic's radio, Tails warned Sonic that Amy Rose has been captured by Dr. Eggman, but Tails cut out and Sonic only heard part of the message. Afterwards, Eggman made an announcement that he had in fact captured Amy and Sonic ran off to save her.

Stage LayoutEdit

Throughout the stage Dr. Eggman continuously makes threats to hurt Amy. Located in various places are switches that can control gravity. Using these switches, Sonic can solve the numerous obstacles that come his way. There are also rails on the ceiling and different "colored blocks" that float in space. Using the Low Gravity switches the player is able to navigate through these blocks.


The Upgrade for this level is the Flame Ring, it allows Sonic to break Steel Containers. It creates a ring of fire around Sonic as he does the somersault move. This upgrade is required to beat the stage.

  • Sonic Adventure 2 on the Dreamcast had boxes with a green X on them, but in Sonic Adventure 2: Battle these Xs were red because SEGA feared that they were competing with Microsoft, since the X in the Xbox logo was green.
  • This stage makes a return in Mario & Sonic at the London 2012 Olympic Games. It is where the Dream Trampoline event is held.
  • In the Dreamcast and digital re-release, Big the Cat can be seen waving in outer space into a window.
