it's a huge modified truck with fork and spoon arms that scoops up unwanted food onto a plate which then dumps onto a bucket that launches it into the north hills. It moves on caterpillar tracks (worked by a clockwork mechanism) and two front wheels. It's also taller then the average semi truck and with top megaphone & pop out caution + stop sign
It first appears in a broadcast by Sam Sparks introducing the vehicle after being manufactured.
It's also seen scooping unwanted ice-cream on Cal's birthday.
The Outtasighter is similar to a truck used by the Sanitation Department of Chewandswallow to clean up after each meal in the book.
