Mystic Frog

The Mystic Frog is a Critter that spawns in the Jungle. It is one of the few creatures detected by the Lifeform Analyzer. When Purification Powder is applied, it turns into the The Mystic Slime.The Mystic Frog glows a faint light when in the dark. If attempted to catch with a net, it disappears into a puff of smoke, similar to the behavior of a critter spawned from a statue.

Most of the time you can find it within 30 minutes.

It's just a chance though, good luck!

Monsters can kill it like with any other critter.

Spawning

 * Gnomes and Water Candles and/or Battle Potions can be used to increase its spawn rate.
 * Having a town of 3 or more NPCs nearby will greatly reduce enemy spawns while also increasing critter spawns.
