BERLIN (AP) — An entire troupe of performing fleas has fallen victim to the freezing temperatures currently gripping Germany.

Flea circus director Robert Birk says he was shocked to find all of his 300 fleas dead inside their transport box Wednesday morning.

The circus immediately scrambled to find and train a new batch so it could fulfill its engagements at an open-air fair in the western town of Mechernich-Kommern.

Michael Faber, who organizes the fair, told The Associated Press that an insect expert at a nearby university was able to provide 50 fleas in time for the first show Sunday.

Faber says he hopes they’ll “get through this without any more fatalities.”

Birk said it was the first time his circus had lost all of its fleas to the cold in one go.
