The Society of Distinguished Lemmings

In a society of lemmings, can a bear ever belong?
The Society of Distinguished Lemmings enjoys the finer things in life, and its members aim to be distinguished in everything they do. But it takes lots of rules to be so distinguished, like: no rolling around, no climbing about, and certainly no splashing in the mud!
One lemming by the name of Bertie has had quite enough of the rules. So Bertie ventures outside, and there he discovers a bear. The bear shows Bertie that prancing about in the wild is quite a lot of fun. But the other lemmings decide at once the bear is not at all distinguished! Will Bertie's new friend ever fit in, or is the bear simply too big and clumsy?
