Beeble
Native to Dominaria. A Beeble is a magical construct similar to a homunculus used by the researchers, tutors and students of the Tolarian Academy as a convenient, easily summoned demonstration subject. They are small, slightly larger than a fist, have bare, rounded bodies ranging in color from pink to blue, and a set of feathered wings. They are permanently, even infuriatingly cheerful, mischievous but not maliciously so, and seemingly indestructible (though they can be unsummoned). Because of their irritating and bewildering nature, students loved to use Beebles in practical jokes, and Teferi once tied a pair to his feet to bounce tremendous distances.
Beebles were apparently based on artist Jeff Miracola's depiction of souls on the card Equilibrium. In the game, beebles were used as comic relief during the Artifacts Cycle of sets.
