Even something as simple as a pacman(Horned Frog) would take time and space to mass breed.

That's too bad.
I know that where I grew up, it sometimes seemed that nature itself was breeding them primarily as a feeder item.
Their survival rate, from egg to frog, must be something like two out of a hundred, if that much.
Btw - there's a special word for frog eggs in German (Laich) - is there one in English?
