"Pfeffer today attempted the life-threatening Feint with awful consequences, failing to pull out in time and colliding with the ground at what onlookers estimated to be sixty miles an hour."
-- match report Wales v Germany, Daily Prophet, 22 May 2014 (Pm)
During their first match against the Welsh side in the Quidditch World Cup 2014 tournament, Pfeffer was fooled into a steep dive by the Welsh Seeker's Wronski Defensive Feint. Although Pfeffer broke most of his bones - and thought he was now a bird - his manager Faust thought he would make a complete recovery following further treatment. Germany lost the match by 330 points to 100 (Pm).
