The beginning
The parts of this series will vary. Some images will have the story written in the descriptions, others may not. Some images may be colourless sketches, or simple drawings with little to no detail/shading while some might have more detail
TYT episodes Baby Critters and beyond are non-canon. In the MYM timeline, I’m not too sure where this fits (I have no plan for Misty or Opaline to have any major appearances, if any at all) So it can be your guess for now
