During band practice, some unexpected guests interrupt. Papa and Mama Vole (and all their young'uns) pop up to see if they can bunk with Hal. They're having a little problem at their burrow so they need to find shelter. Hal is happy to have the company at first, but when the voles start to take over and eat all his plants, it's time to ask the voles to leave. Easier said than done, as getting the voles back in their home sets off a chain reaction of other animal habitat problems!
