Big Bird approaches Luis who is working on a cuckoo clock on the bench in front of the Fix-It Shop. Luis is having trouble fixing it, so Big Bird suggests keeping it warm and giving it lots of juice until it gets better. Luis tries to explain that it's a mechanical cuckoo, but when the clock strikes the hour, the bird emerges and sneezes. Two alpine climbers hike up a letter Z and stake a claim on it. Z for zipper.
