Dream Worker VIP: When a Dream Worker VIP is delivered to a floor, it will change one Bitizen's dream job to match their current job. If all Bitizens on the floor are already at their dream job, the VIP will have no affect. The Dream Worker VIP can now be delivered to a Commercial or Residential floor.
Real Estate Agent VIP: When a Real Estate Agent VIP is delivered to a residential floor, it will fill any available 'for rent' slots for that floor. There is no effect when delivered to Commercial floors.
