Tam-Tam is a character first appearing in Bust-A-Move 4. He is the totem pole Lord Protector of the planet Navajo.
The North American Dreamcast booklet describes him as this:
"He is the Lord Protector of the divine Navajo planet. He is the father of the wind and the earth, and is capable of being hostile or gentle. He senses incidents of evil, and soars into space in pursuit of the wonders of night...the night which now never ends...the morning which never comes."
