A wordless sequence that would have benefited from a few strategic words of explanation--words which, however, would have given away the single, unoriginal point of the whole affair. As we see events unfold, an invitation arrives which somehow includes every animal but poor pig; at least, they all head off somewhere while he tails them. . . and then contrives to trip up bear, who's leading the procession on his unicycle. All the animals take a header over an adjacent cliff, and land harmlessly in a haystack, next to which stands a birthday cake; and with the appearance of mama pig, and the puzzled little pig himself, we learn that what everyone but he has been invited to is his birthday party. Befuddling if you don't know it's pig's birthday, and rather lame if--from the jacket--you do.
