Mystic Frog

Overview
The Mystic Frog is a Critter that spawns in the Jungle with a 3.33% (1/30) chance to spawn in place of a regular Frog. It appears as an orange and pink frog with a large pink sunhat and glows a faint light in the dark.

When Purification Powder is used on it, it turns into the Mystic Slime, a Town NPC, similarly to how the Tortured Soul transforms into the Tax Collector.

Tips

 * The Guide To Critter Companionship will prevent the player from killing the frog accidentally.
 * Gnomes, Water Candles, Battle Potions, Coin Luck, Blood Moon and Solar Eclipse can be used to increase its spawn rate. Note that Water Candles, Battle Potions, Blood Moon and Solar Eclipse also will increase the spawn rate of enemies which can kill it.
 * Having a town of 3 or more NPCs nearby will greatly reduce enemy spawns while also increasing critter spawns.
