Well, in the Care Bears Movie, they find the Care Bear cousins (which are basically other animals like a raccoon and elephant,etc.). One of the care bear cousins was a pig.
I think his (or her?) name was True Heart Pig.
I know that may not be the answer to your question, but maybe that's what you were thinking of....?
Try looking over the Imdb site for the Care Bear movies and try asking on the message boards down at the bottom to see if fans might remember.
