Feed the Mimic!

The mimics each eat a maraca, shaking them wildly in their stomachs. They give you a wonderful song.

I feed the mimics a scrambled-up Rubik's cube...

They both eat the Rubik's cube without suffering the "insanity of the plastic materia"....

I start crafting a Grotesque statue about those mimics and You..........

The mimic gladly gobbles up the statue, spitting back out a red tongue.

I feed the mimic the Beyond Heroes cast

 It spits out the Mighty Nein

I give one mimic a top hat and bow tie and the other one a veil and wedding dress.

"I'll be the parson!!" I gleefully squeal to the mimics

The mimic gives you a dirty look, and eats the “wife”.

I feed the mimic John Cena.

The Mimic eats John Cena just as he casts invisibility on himself. "You can't see meeeeee" He screams while being eaten. And the Mimic then opens his mouth wide kinda like a snake and fog rolls out of the Mimics mouth as the Undertaker slowly marches forward. 

I stand in shock of the Undertaker and accidentally drop half my bag of dice into the Mimic. Dang it.

The mimic spits out a nat 20

I feed the mimic a pickled egg

It spits out a pickle with an egg on it.

I feed the mimic my character (a dragonborn light cleric)

The mimic spits your character back out and has bestowed upon your character a Powerful Blessing. You now have the ability as an action to summon or dismiss a golden ethereal celestial version of your self made from light (similar to that of the Dancing Lights Spell) at will. If you fall unconscious this light being is dismissed. While active you add Dancing Lights; with no concentration required, Color Spray, Moonbeam, Wall of Light, and Call Lightning to your spell list. The light being can move on your turn up to 30 feet, and can have touch based spells and effects cast through it.
