The manager of the "Gugu-Gaga Diner." Versatile. Can handle being both a chef and a waiter. It's a mystery why the shop isn't popular despite having such an amazing manager... Initially, the Gugu-Gaga Diner sells "Gugu-Gaga Special Fried Rice," "Gugu-Gaga Ramen," and "Penguin Crepes." They are quite cheap and delicious. The menu is supposed to keep growing... probably. Surprisingly stupid. No, actually, very stupid. Can only speak by saying "Gugu-Gaga."

A waiter at the Gugu-Gaga Diner. His waiting skills are incredible. He loves reading. All the books he reads are written in "Gugu-Gaga-ese." He can write characters and even makes the menus. He understands human speech, but he is terrible at writing it. Just like the manager, he is surprisingly stupid.
