Originally I wasn't going to get Lana or Tanky all that wet, but there were a couple of ideas that I had for Chapter 27 that I ended up not implementing. Then I figured out a way to maybe open Chapter 28 with a similar idea. That would require that Lana and Tanky get a little wet and soapy too, though.
So then I had to setup versions of them with soap all over them. Thankfully that is not all that hard. :)
