How do you get chroma frogs on pocket frogs?

One way to get the Glass Frog is to breed different frogs in hope of getting one. There is a very small chance that the baby will be one. You can also look for them in the Pond, and breed with them, though they are VERY rare.

OR.....Instead just breed two purple carota anuras and you will 100% get one. You can sometimes win one in a race, if your frog comes first, and you choose one of the opponent frogs as your prize.
