So this is sort of something I suggested before in April, but I'm refining it and expanding on the original idea. So it's a bit different.
Originally I was thinking for Christmas we could take the black and white pets from April Fool's and have them painted again, since we did have some of the April pets B&W. But, not many of them stayed that way.
So my revised idea was for Totoro to still come with her paintbrush to repaint some of the black and white pets, but also to some of the other B&W pets from this year with her paintbrush, painting them color, trying to make up for her April Fool's Day prank.
