Mobster from Dimension X

Dr. Alvin Huxley has demonstrated his breakthrough invention: The Protein Computer, a computer that thinks as fast as a human mind and can be linked to one. When some gangsters break into the Professor's lecture and try to kidnap him, the Turtles arrive and drive the gangsters away. But these are not ordinary gangsters as their boss is is the Globfather, a large slimy green amoeba in a pinstripe suit and fedora. The Globfather is on Earth and wants to get the protein computer for someone who is willing to pay a lot for it.
