As night falls, the trio listen to a music program on the radio, which is interrupted by a news bulletin about a deadly panther that has escaped from the local zoo earlier that morning and has been reported in the Lake Woebegone area.

Believing the news, Garfield is terrified and wants to leave, but Jon assures him that Lake Woebegone is miles from their location and that they're perfectly safe.

At Garfield's suggestion that he "go and play with something poisonous", Odie runs into the nearby woods, passing a sign that reveals it to be Lake Woebegone, where the panther is lurking.

To make matters worse, Jon discovers that Garfield and Odie have eaten all of the food for the week, except for the dried fruit, and so he goes off on a tirade.

Odie appears, after scaring all but Garfield away by accident, and the two eavesdrop on the two rangers passing by with a tranquilizer gun, hoping to capture the panther.

Garfield and Odie decide that now is the time to collect Jon and leave before they are possibly attacked by the beast, and the two run all the way back to the campsite.

However, the full moon comes into view and shines down on the camp, revealing that the panther has now entered their campsite and is approaching the trio as they look on in horror.

Garfield recovers as the now-enraged panther begins to menacingly creep towards him and lunges at him in an attempt to kill him, until the park rangers enter the campsite and subdue the beast with a tranquilizer dart.
