The Care Bears Movie
The Cloud Clipper is used as a way for the remaining Care Bears to leave Care-a-Lot and find the others, re-discovering the Care Bear Cousins along the way. This version of the Cloud Clipper is in fact made of clouds, and has a star for a sail.
A New Generation
In the 2nd movie, the Cloud Clipper was used by Noble Heart Horse and True Heart Bear to take the young Care Bears and Care Bear Cousins to safety in the Kingdom of Caring. While on its way, the boat was transformed to look more cloud-like by the Great Wishing Star, and remained in this form for the duration of the original series.
Care Bears and Cousins
In the 2012 incarnation of the franchise, The Cloud Clipper is mostly piloted by Brave Heart Lion, and takes on a much different appearance, becoming more wooden once again, and more mechanical than the typical cloud make up of most Care Bear objects and technology.
