If your like me and you love spreadsheets and checklist to help feed that OCD completist in you, then here is a must have. I put together an Excel spreadsheet of all the pets currently known along with there locations and F2 abilities. YES I know that most can be found in multiple locations, but I listed one for ease of use. I also left a bunch of blank cells in the end for one's I may have missed. Please update this thread if you find one I missed so I can update the checklist. Thank you
