I had one not long ago, with MAJOR Hyperactivity Disorder that RAN absolutely everywhere. This sounds good because it means she could do farming quicker, in theory. BUT, when she harvested the crops, she'd ran with the basket, spin around and fly smack bang into the food bin and the basket would fly out of her hand, so she'd lose the load! Same with building. She'd get a stone to build with, ran back and it would fly out of her hand before she got to the building site. A real waste of time.
