The Millionaire Cow is a cow statue that will produce 1 RC per day for a limited time. The cow does not need to be cleaned by neighbors before giving a RC.

 

A Millionaire Cow discount will pop up automatically if you have never purchased a Millionaire Cow before and you can only purchase it once.

 

After you place it in your farm, you will get 10 RC right away. Further it will produce 1 RC per day with or without being cleaned by neighbors. If you skip a day, your turn will be shifted to the next day, so you are guaranteed to receive the promised amount of RCs.

 

When your Millionaire Cow is cleaned by a neighbor, the neighbor will get a cleaning box but you won't get anything extra. You can only collect RC from it.

 

After you finish collecting all the RC from the Millionaire Cow, you can reactivate it again by purchasing the Millionaire Cow extension package by tapping on the Millionaire Cow itself.
