Getting kids to go to sleep when you want them to can be difficult. ``The Pajanimals'' hope to help accomplish that task. The four cuddly friends on the show snuggle together each night to sing sweet nighttime songs to their preschool friends at home. The puppet characters include bossy dog Apollo, energetic duck Squacky, quiet horse Sweetpea Sue, Italian cow CowBella and the unseen Mom and Dad, the parents of the Pajanimals. ``The Pajanimals'' is produced by The Jim Henson Company, veteran producers of children's programming.
