If you're a monster and you know it, wave your arms,
If you're a monster and you know it, wave your arms,
If you're a monster and you know it,
Then your arms will surely show it, *
If you're a monster and you know it, wave your arms
If you're a monster and you know it, show your fangs...
If you're a monster and you know it, stomp your feet...
If you're a monster and you know it, show your claws...
If you're a monster and you know it, growl out loud...
- alternate line: And you really want to show it
