Lyrics: TV Themes. Thundercats.

[Lion-o]

Thunder, thunder, thundercats, Ho!
Thundercats are on the move,
Thundercats are loose,
Feel the magic, hear the Roar,
Thundercats are loose,

Thunder, thunder, thunder, Thundercats!
Thunder, thunder, thunder, Thundercats!
Thunder, thunder, thunder, Thundercats!
Thunder, thunder, thunder, Thundercats! Thundercats!
