The Terrible Twos of Slitherlink Part Deux

Please read and understand my first question before proceeding. This one should be worse.

Slitherlink of Twos



Their solutions



These puzzles were generated by computer. A good solver has no problem solving them, so I can't just ask for people to find the solutions. That's why I'm just giving the solutions to you up front. Fair warning, these are super hard to solve by hand.



I did think of a different question I could ask, but we need to define some things first.



A Slitherlink of Twos is a typical, square cell, Slitherlink puzzle where each cell is either a "2" or left blank. It may have any grid size, even rectangular ones, just nothing weird like an "L" shape. It must have exactly one loop for a solution.



Let us also define backfill as the process of, having solved a Slitherlink puzzle, going back and filling in each blank cell with the appropriate number for the solution.



As we learned from the previous question, for a Slitherlink of Twos, we would expect that when we backfill a typical puzzle we would at some point be adding ones or threes.




Can you, when you backfill any Slitherlink of Twos, add a zero to a cell?
