Fort Cobalt barista
From the Super Mario Wiki, the Mario encyclopedia
The Fort Cobalt barista is a character in Paper Mario: Color Splash, an inconspicuous red Toad running the Prisma Café in Fort Cobalt. He sells Hearty Lattes for 70 coins, Prisma Juice for 120 coins, Magma Burgers for 200 coins, and a "Special" for 100,000 coins. Hearty Lattes fully restore Mario's HP, while Prisma Juice fully refills Mario's paint counter. The barista claims the Magma Burger is a popular item. The first time Mario purchases one, he receives a one-time only "Booyah Meal", containing the Fishing Pole. The barista claims the one Mario is sold is the last one in stock.
If Mario orders the "Special", the barista checks to make sure he really wants it. If Mario accepts, the Toad suddenly becomes serious, telling Mario to act natural. He informs him his café is a front, and that he is a spy. He tells Mario he has acquired intel about a special Battle Card effective against the superweapon they are developing. He gives Mario three Tail cards, essential for counterattacking. The barista tells Mario he is constantly collecting information and to check back with him in need of assistance. After this discussion, the barista perks up and sends Mario off. As a bonus, Mario is able to get this information for free, rather than having to pay 100,000 coins.
Toad #4 of the blue Rescue Squad can be found in the middle locker to the right of the café, drinking coffee the barista supplied him with.
