Grizzy and The Lemmings (31)

The Lemmings throw a surprise birthday party for one of the clan. When "Happy Birthday" rings out, the surpriiiiiise! is as great for Grizzy, who is trying to take a nap after a hearty meal, as it is for the birthday Lemming hero in question. From that point on, Grizzy has only one objective: stop the din, which is not at all helping his migraine headache. But for the Lemmings, the party must go on at any price.
