Originally, I think I was trying the fish w/bait at his own pond which didn't work. When I went to Sylvan Glade, I was able to do it. Maybe any other place except the home lot works. I finally completed the "catch or breed 8 common frogs." I'm not sure how b/c I had 8 different common frogs, but it wasn't registering. My last assignment is to get a 4th rare frog. I have the Sunsurfer, Eggplant Whirl, and Surfer Eggplant. Do you have any tips on which frogs to breed to that a different rare?
