WILD WOMBAT CHALLENGE
Accept: +3 points to your group; the entire group must complete the challenge to the instructor's satisfaction
Decline: Force another group to accept the challenge, BUT they get the +3 points (and you get none)
Your group must strut one lap around the room as ducks to "The Duck Song". There must be wing flapping, squonking/singing, and a proper duck waddle.
Now, waddle away, waddle waddle.
Bonus Point Madness! +1 extra point
