Lost lake is a popular 102-acre park in the San Francisco Bay area. It first appeared in "Gone Fishing " when Marvin and the gang decide to fish, hike and picnic there on a day off that didn't go as planned. It reappears in "Marvin and Eddy in the Middle of Nowhere " when they decide to go fishing without telling Jack causing him to worry about their absence.
