WASA is the Worm Air and Space Agency, the worm equivalent of NASA, located at 25 Wiggle Way Station in the Cape Canaveral Mud Flats. In a 1998 Sesame Street episode, the agency recruits Slimey for a mission to the moon. Staffed by a training officer and several highly trained worm technicians, they oversee the testing of a team of brave astronauts. The roster includes Spaghettini from Italy, Squishta from Romania, Legusano from Colombia, Squashimi from Japan, Slogoshki from Poland, other worms from Puerto Rico and Zambia, and Selma Worm, who is actually a chicken dressed as a worm.
