One thing leads to another when you give a pig a party.

Pete, a practical pig, has his life intruded upon by Pickles, a runaway circus elephant that needs a friend, and the two dive off Niagara Falls, careen down the Matterhorn, and engage in other adventures until their friendship wears thin.

Elephant, who is cautious and pessimistic, and Piggie, who is optimistic and sometimes reckless, go outside to play in the sun and hope that it does not rain.

Adaptation of E.B. White's novel about Charlotte the spider and her friendship with Wilbur the Pig.
