Chakroad

The Chakroads are special portals located across the Mushroom Kingdom in the game Mario & Luigi: Bowser's Inside Story. They are described as "gateways to special waves that flow to earth from outer space." The King of the Koopas, Bowser, uses there portals to warp to different locations throughout the course of the game. Bowser first encounters a Chakroad in the Cavi Cape after being prompted to smash a rock by a strange voice telepathically connected to Bowser's mind. After uncovering the first Chakroad, the voice explains that these portals can be used by Bowser to travel to places he has already visited (and discovered the respective Chakroad for), doing so through the power of his mind and memory. Chakroads can be found under objects such as rocks, which can be destroyed with a punch, or trees, which can be burned away by fire. It is later revealed the the Chakroads are connected to the sage known as Chakron, likely given his own connection to outer space after meditating on the stars for a thousand years.

Locations

 * 1) Cavi Cape Entrance: Under a boulder. Break with a punch.
 * 2) Cavi Cape Exit: Under another boulder, near the tunnel that leads to Bumpsy Plains.
 * 3) Plack Beach: Hidden below a palm tree that has to be burned.
 * 4) Dimble Wood: Hidden below a tree.
 * 5) Bowser Castle
 * 6) Underground Tunnel: Under a crate.
 * 7) Lake-Plain Border: Under a giant Brick Block.
 * 8) Peach's Castle: Under a Fawfulfied Princess Peach Statue.
 * 9) Top of Peach's Castle

Since Chakroads are always hidden under objects that only Bowser can destroy, the Mario Bros. can never use Chakroads. If the portals are already unveiled, the brothers cannot see them either.

Trivia

 * The name Chakroad is a portmanteau of chakra and road. In Hinduism and Buddhism, the chakras, or energy centres, are special focal points located on the body, described as whorls of received and transmitted energies.  Similarly, Chakroads are depicted as whorls of energy that form special "focal points" for Bowser in the Mushroom Kingdom.
