Topic, Level "Electric Leather", game "Puzzle It"

  That's right.

  I changed the title from "Leathers Electricity" to "Electric Leather", which makes more sense. Leather is a material, and that's why it is written without an 's'. I guess the solution is by passing around the smart walls?

  First, have separated the brown blocks.
Same as sv's Study level. You know?
Is there a lot of leather(s), but is it better to subtract (s)?

  It looks impossible. Could you prove it is possible?
