The most valuable tip that I can give you is to pay attention to your Froggydex. With the help of your Froggydex, it is possible to identify an egg before it hatches.
As soon as an egg is layed, your Froggydex knows what breed of frog the egg will become and will update accordingly.
Let's say that you want to breed a Maroon Tingo Anura.
- Maroon Tingo Anura is currently blank in your Froggydex
- Breed the correct colors/breeds to get a Maroon Tingo Anura. Breed as many frogs as you can afford or as many frogs as will fit in your Nursery to give you the best chances to get your desired frog.
- Check your Froggydex to see if the information for Maroon Tingo Anura gets filled in
- As soon as you see the Max Value and Speed/Stamina information, you know that one of your newly laid eggs is a Maroon Tingo Anura
- Remember the Max Value from the Froggydex and go back to your Nursery
- Find the egg(s) that has a matching Max Value. This egg will grow up to be a Maroon Tingo Anura
- You don't have to wait for the egg to hatch to find out its breed
This strategy works for any breed/color combination.
From here, you can sell off the unnecessary frogs to make room for more eggs.
