Sensor Lab

The Sensor Lab is a location in Picnic Road in Paper Mario: The Origami King. Its main use is to allow Mario to "fax travel" to satellite offices located in other regions, although the main lab is not accessible until unraveling the red streamer that is wrapped around it. When the Sensor Lab is visited for the first time, Mario can activate it by hammering the "yellow mushroom" on the fax printer, revealing the Toad Researcher. As thanks, he gives Mario the Toad Radar, along with a chance to test it. The Lamination Suit and Hidden Block Unhider are also invented at the Sensor Lab after entering Scorching Sandpaper Desert and transporting the Super Marino out of the Musée Champignon, respectively. These tools can be charged at a lab location for 500 coins each.

Satellite office locations
The satellite offices are activated by filling a Not-Bottomless Hole signifying their location, then going inside and pulling the researcher there out of the receiving end of their fax printer.
 * In Autumn Mountain, by the bench near the Water Vellumental Shrine. Its interior is red.
 * In Shogun Studios, near a Ninji looking for a Straw. The Shogun Studios Master Key is required to reach it. Its interior is blue. If Mario fax travels to this satellite office, a Blue Toad will forcefully escort him to the park entrance, showing Mario knocked off his feet afterwards.
 * In Scorching Sandpaper Desert, on a ledge to the south west of the tower. Its interior is green.
 * On ? Island, on a ledge with a treasure chest next to the door. Its interior is purple.
 * In Shangri-Spa, behind the entrance building. Its interior is white.
