Boiling a frog has landed Bear Grylls and Derek Hough in hot water with Bulgarian authorities, thanks to an episode of “Bear Grylls Running Wild” the two filmed in 2017.

As The Guardian reports, the adventure-seeking TV host and his special guest camped out in Bulgaria’s Rila mountains, where food was so scare the pair were forced to kill, gut and boil a frog, which they proceeded to eat, and then went swimming in the lake.

Unfortunately, swimming, lighting a fire and killing animals — even amphibians — are all prohibited in the protected area where they were camping.

“It is evident from the film material that during the shooting there were breaches to the regulations and rules of conduct in protected areas: entering and swimming in the water basin of the Karakashevo lake, lighting a fire, and catching and killing an animal,” a spokesperson for Bulgaria’s environment ministry said in a statement.

According to The Guardian, the show’s production company could be fined anywhere from €500 to €5,000 ($750 to $7,500 Canadian), while Grylls and Hough could individually receive fines of between €250 and €2,500 (CDN$370 to $3750).

It remains to be seen whether the environment ministry will institute the fines.
