Frog dinners sustained a man trapped on a small island after a local flood wiped him out of the forests.

Zdenek Bucek was taking a short-cut through the woods near the southeastern town of Breclav when, according to the daily Pravo, he was swept away by a wave of water.

"I had no idea a flood was coming. I had not even noticed that the forests were declared off limits," 30-year old said.

Bucek said that a diet of frogs and other small animals kept him alive until he was saved by an emergency crew passing by on a boat four days later.
