Moppo can be purchased using Dinero from the Greasy Spoon Restaurant Store.
 
When you have Moppo, any customer spills will be automatically taken care of by Moppo!
 
- Note that if Flo walks in the path of a spill before Moppo gets there, she will automatically clean the spill herself. Moppo can only clean one spill at a time, so Flo might still have to lend a hand.
