The Mimic Chest & Treasure Dice

Opening the ornate door in the castle's underbelly, your party’s torchlight reveals a treasury containing marble statues, a collection of fancy hats, and—wooden chests! 

Unlatching the nearest chest, you reveal glittering faceted gemstones! Emeralds, sapphires, rubies, and more! Your companions cheer and pry open nearby chests, scooping up mounds of jewels for themselves.

As you fill your pockets, a royal-hued amethyst in your hand blinks. Wait. Blinks? Some of the "jewels" in your pocket begin to squirm, opening eyes of their own. “Mimics!” you bellow as multiple chests spring to life in your peripheral vision. 

Before you can flee, a sticky blue tongue grabs your arm, a mass of green eyes fix their gaze on you from the chest's lid while teeth reach out from its front and sides. You release the jewels from your hand and they noisily clatter and clack as they come to rest. Your party engages in battle! 

Surveying the scene excitedly, you turn to your friends and exclaim, "Wow, these mimic chests and jewel-mimics are incredible! They’d look amazing on my shelf. Let’s grab as many as we can!" How many mimic chests, jewel treasures, and jewel-mimics will your party collect?
