Pi'illos are an ancient species who inhabit Pi'illo Island, appearing in Mario & Luigi: Dream Team. They have pale pink skin, hats resembling pillows, beady eyes and small feet. Similarly to Toads from the Mushroom Kingdom, Pi'illos are almost identical to each other, with few having distinct appearances, and wear different colored clothes as reference. With a few exceptions, they lack bodies in the dream world. The members of the species can apparently become pillows, which serve as portals to the Dream World. In fact, their name comes from the word "pillow".
Prior to the events of Dream Team, the Pi'illos were the guardians of the Dream Stone and the Dark Stone, two spiral-shaped rocks containing tremendous power. However, Antasma - the bat king and the game's main antagonist - managed to steal the Dark Stone in his attempt to fulfill his own twisted wishes. The Pi'illos engaged Antasma in battle to prevent this, but just before he was sealed away in the dream world Antasma shattered the Dark Stone: the resultant chunks of the Dark Stone petrified every last Pi'illo in existence, causing others to presume them to be extinct until Mario and Dreamy Luigi freed Prince Dreambert towards the beginning of the game. At Prince Dreambert's request, the bros. set out on a quest not only to free the remaining Pi'illos (something Prince Dreambert himself could not do), but also to rescue Princess Peach from Antasma with the Pi'illos' help.
Types of Pi'illos
The majority of the Pi'illo race ended up getting hit by nightmare chunks, many of them were trapped throughout Pi'illo Island. There are a total of 52 Pi'illos that can be freed in this game (53 counting Prince Dreambert who isn't counted by the game), though only 21 (40% rounded) of them are mandatory.
