This was one of the CREEPIEST toy jingles of my childhood.
The Inchworm was a toy for little kids. It was plastic and industrial spring contraption made for ADHD kids with uncontrollable urges to bounce around everywhere.
You could only ride it on flat, level sidewalks. Hills would either send you backwards going up or accelerate at demonic speeds going down.
It wasn't made for overweight kids either.
