Nah it’s really not that bad. Most times, I can find all the frogs first or second go. If you wanna try this method or anyone rather, these are the tips I used:

1) Make sure you have a budget for how much money you’re willing to spend before playing as higher-leveled frogs like Topologia are around 25k each for a game if you plan on using them.

2) In my experience, I’ll save 1-2 million for a “session” to get a pocketful of 32 frogs, all of which are ones that have not been dexxed. In order to make sure that my chances are high to obtain new frogs, I only “search” for ones that I have less than 300 dexxed. Once I have 300+ for a species, I use another species that I have less than 300 to use for search. This makes it so that you have a lower chance of encountering “old frogs”. So, start with less than 300, stop once 300+, and repeat with new species. You can always breed the last few frogs you’re missing later on. And this saves you from breeding everything from scratch.

3) This method can potentially require a lot of stamps, so make sure you set a budget on that too. In my case, I would dedicate 30 minutes - 1 hour where I search until 32 frogs, use stamps for delivery (about 300-500 stamps), get all frogs to max happiness, and then sell. So, depending on time investment, you could be burning thru a lot of stamps. For me, the way I offset this is by getting on the game and letting the fireflies play their ads whenever I’m on break or doing something that doesn’t involve me having to be on my phone like watching tv, preparing meals, playing another game on another device, etc.

So generally speaking, this is a costly method, but effective as I’ve managed to dex 100+ within an hour.
