The attraction features a coaster track that Andy Davis has built all over his backyard using his Mega Coaster Play Kit when he will young, he has a pretty amazing imagination, so he’s combined it with some of his other toys, according to Imagineer Kathy Mangum. Take a look at a concept video of Slinky Dog Dash that Kathy shared earlier.
On the ride, guest will zip, dodge and dash around many turns and drops that Andy has created to really make Slinky Dog and his coils stretch to his limits.
A quote from the Disney Parks channel it's self
"It's made to make riders feel like it's the slinky dog coaling and uncoiling in the drops and turns"
I think that's what was said I'm not exactly sure if it was the exact quote said but still
