Asterix A'r Cur Pen

The bighead traitor Dwishobodynsaix has gone over to the Romans, and uses an old Gaulish tradition to fight for control of Asterix and his tribe. But druid Gwyddoniadix has had an accident with Obelix's menhir, and the magic potion has all run out, which means it's all a bit of a headache for chief Pwyllpendefix!
