It's Christmas time and Clark decides to invite all the family to have 'the most fun-filled old-fashioned family Christmas, that no one will ever forget.' When the first relatives arrive, Clark goes out on the roof to rig the lighting. The one thing that Clark wants is to surprise the whole family with is the installation of a pool, which he already ordered. Unfortunately, the bonus check Clark expects any minute is overdue. Tempers rise and not just...

Kermit, Oscar, Bert, Ernie and Cookie Monster join Big Bird in a bighearted, cross-country adventure. A meddling social worker sends poor Big Bird off to live with a feathered foster family in Illinois. But try as he might, he doesn't fit in and runs away to return to Sesame Street. Now his old friends need to find him before he runs 'afowl' of trouble en route.

A group of friends must step forward as unlikely heroes to recover three magic diamonds, reverse the onset of a brutal winter and return the evil ice sorcerer Zeebad to his prison beneath the ground.
