best way is to participate in raid, get brave medals. use the medals at the slot machine. it has a pretty decent chance of dropping frogs, plus other stuff. otherwise, do monday exp dungeon last stage. it very rarely has a burst frog in the middle fight, however it is not a guaranteed chance to capture. on other days, you are better off using your energy to farm bb fodder units from quest maps. higher level maps yield higher level bb fodder that in turn is more likely to lvl up your unit's bb.
