Aogaeru, a greedy little frog spirit and worker in the bathhouse from Spirited Away. He spends most of the movie being swallowed by No-Face, who takes on several characteristics of Aogaeru, including his greed, his voice and his frog legs.
Most male workers in the bathhouse are frog spirits and most female workers are slug spirits. No explicit explanation is given in the movie, but it might be a nod to The Tale of the Gallant Jiraiya, a Japanese folktale featuring the toad-riding Jiraiya and the slug-riding Tsunade. They had frog and slug based magic abilities respectively, more on them in the future.
