If the devs need a new revenue stream from Dream World, how about this idea: Toll booths. There are a lot of roads in Dream World, and if toll booths were installed so players had to pay it would generate a nice amount of profit for the developers. They could also accept livestock, fruits and vegetables, and small children. They could be used to fetch beverages or upkeep on the property.
They could even create a charm that would waver the toll fee.
Just a suggestion...
