Konatsians

From Dragon Ball - Wiki on Neoseeker

The two Konatsians Tapion and his brother Minosha appear in the 13th DBZ Movie. If it were not for their pointy ears, they would look just like humans in appearance. Their people appear to be rather noble and their world quite royal. Tapion and Minosha in particular are swordsmen, who both have mystical ocarinas that when played were able to stun Hirudegarn.

Tapion and Minosha then were able to each trap a half of Hirudegarn's body within themselves, and then trap their own bodies inside music boxes so that Hirudegarn may never escape. Minosha was later killed when his half of Hirudegarn escaped, and when the monster was eventually killed by Goku, Tapion left the Earth via Bulma's Time Machine and gave his sword to Trunks.
