Kidd Gruff, known as Yagi Kenta (八木ケン太 Yagi Kenta?) in Japan, is a young boy from a small town in the Loch Mess area. He met his FM-ian partner, Goat Foo, at Alohaha. When they combine, they become Kung-Foo Kid, a wood-based martial artist known for his exceptional speed. Neither Kidd Gruff nor Goat Foo appeared in the anime.
