My collections are 0 for 6 with Thomas. 1 for 2 with Ivy, 0 for ? with the mines (No idea if they were sparkling or not). The one Lynx dropped 3 pelts.
I have had the sound on the entire time to ensure I didn't have any other monster on the board. The drop rate from the flowers has been great. I wonder if I will max the wild flowers before I can upgrade the pasture to lvl. 3.
