Taste my ancient tusks that have awakened 
from their ten-thousand-year slumber-moth!
تذوّق أنيابي القديمة التي استيقظت
 !من سبات العشر ألاف سنة
Friss meine uralten, aus ihrem zehntausend-
jährigen Schlummer erwachten Stoßzähne!
Après un long sommeil de 10 000 ans,
goûte à mes défenses de mammouth !
