The Dawn Pustules are fruits in Pikmin 3 that are actually white grapes. They are found in bunches of 20, and must be individually plucked, exactly like the Dusk Pustules. There are only two bunches in the game, the first one is in the Distant Tundra and the second one is in the Tropical Wilds.
Captain Brittany's Notes
"These little spheres have it all: smooth skin, delicious juice, a nice smell... They're almost perfect, except that exact shade of green is the captain's, like, favorite color of all time. He painted his room, his fingernails, and (I heard) even his dog this color. Bleh."
"In colour and shape, these remind me of the Captain in his stupid green suit. Lots of little Captains! Eugh. Luckily, the resemblance ends there. Smooth skin, subtle scent, refined taste. Not like the Captain at all, then!"
