Morph

Morph is a pink blob of space goo that has the ability to morph into anything he wants. Silver found him and took him in as a friend and pet. In the movie he plays a trick on Jim by transforming into the Map and there by reviling that the real map was still on the ship, which the crew had stolen. When Silver talks with Jim, trying to bribe the map from him, he calls for Morph to come with him but Morph stays with Jim after seeing for the first time his masters other side, and hearing him say that he cared about only one thing. Flint's treasure. This most likely broke Murph's heart becuase up until that point he thought Silver really cared about him.
