Wall-Climbing Transformable Robots

What are the “Stickers” and where does one get these?

I think the stickers they are referring to were some wall decals in the promotional video we used to include with the description. They looked like little roads on the walls, however they are not necessary for operating the toy so it was a bit confusing.

If you’re planning on getting this for your kid, please watch a youtube video first. These things look to be SUPER loud! They have a vacuum motor in them to make them stick to the wall.
