A flying egg, about to ram the player

Flying eggs are hostile fried egg-like creatures encountered in the Experimental World in Mario Artist: Polygon Studio. When approached, flying eggs will attempt to ram into the player's creation and send it flying.

As with tube creatures, flying eggs are invincible and cannot be attacked.
