So we've been making a custom order that consists of a grundle of beaver finger puppets (the second from the left). That fact alone made my mind start thinking -- I know, a scary thought. Some animals I quickly recognize their collective term. For example, a swarm of bees, a flock of birds, a herd of cows, and a gaggle of geese. But off the top of my head, I couldn't think of what a group of beavers would be called. So how about you? Do you know it? And I mean without the help of the Internet because that would of course be cheating. If you do, go ahead and share in the comments.
