Lord of the Poppies - S4.E39

Grizz, Tabes and the Poppy Rangers head out to an island for their island camping badge. When they forget the lunches, Tabes leaves Grizz in charge while she heads back to the mainland to get food. Grizz, in his usual careless self, misleads the rangers to the point that they become insane savages from hunger and attempt to devour Grizz.
