Dudley and Kitty go to Yellowbone Park to stop Snaptrap, who is stealing picnic baskets. Dudley gets obsessed over T.U.F.F.'s new trailer and refuses to get out of it, but once he does it to go to the restroom, D.O.O.M. steals it. After five minutes out of the trailer, Dudley suddenly becomes a "nature dog" and manages to get the vehicle back, but then it explodes.
