Prince Dreambert

Dreambert is a character who appears in the game Mario & Luigi: Dream Team. He is the leader of the Pi'llow people and thus was among those who were petrified by Antasma; fortunately, he was also the first to be freed of his rocky prison, as Mario and Dreamy Luigi (at that moment trying to rescue the recently abducted Princess Peach from Antasma) freed him from the nightmarish chunk which contained him in the dreamworld by jumping at it. Dreambert explains to Mario, Luigi, and Starlow that there are two powers in the Dream World: the Dreamstone and the Darkstone, which was destroyed by Antasma and used to so thoroughly petrify the Pi'illos that they were presumed extinct. Dreambert requests that the three help free the other imprisoned Pi'illows as they search for Princess Peach. In-game, he explains to Mario how to use Luigi's dream powers to navigate the Dream World.

Trivia
