Using his Mega-Coaster Construction Kit, Andy Davis built a model rollercoaster in his backyard and decided on a whim to use Slinky Dog as a coaster train. As guests are launched from a starting position overseen by the Green Army Men, they begin zooming across Andy's yard. Within one of the coaster's turns, Rex is trapped atop an unstable Jenga block tower which Jessie is roping back into place. At the end of the coaster, before guests reach the unload, an animatronic figure of Wheezy sings "You've Got a Friend in Me" while Mr. Spell offers text comments.[2][3]
