Mendhak, the noted biologist, was stumped. He'd spent months studying with the little green frogs in the Ulaan Baator swamp. The population, despite all efforts at predator control, was declining at an alarming rate.

Finally, Mendhak went to the chemistry department at his local college to see if anyone there might be able to help. Suidae looked into the problem, and came up with a solution. The little frogs had succumbed to a chemical change in the swamp's water, and simply couldn't stay coupled long enough to reproduce. Suidae brewed up a new adhesive, made from a dash of this, a zoss of that, and most critically, one part sodium.

"You mean?.... " Mendhak said when told.

"Yes," said Suidae, "They needed mono-sodium glue to mate."
