Peter is an 11-year-old goatherd, who is responsible for caring for the village goats during the summer. He lives with his mother and his blind grandmother in a shack some distance from the village. His father was a goatherd as well, until he died. Peter's family is not wealthy, and he was used to going hungry until he befriended Heidi. He is an indifferent student, and is somewhat notorious for his greed and academic incompetence; however, towards the end of the animated series he discovers a natural talent at carpentry.
