I remember the Mondo Gecko toy and character in the Archie comics, but I don’t remember him in the cartoon. Also don’t remember Gramma/Grampa turtle either... then again, I only watched the first season or two of Tmnt, then I found the Mirage comics and never looked back.

Are the original cartoons streamed anywhere? I only see the box sets at Walmart or 1.99 per cartoon purchase options on most of the services.
