Mr Blobby was once Baba Papa, the shape-shifting alien who lived with that suburban family. His adventures were shown on 70s BBC childrens' TV. One year, he went with the people he lived with to the tropics. Baba caught a disease that scarred him with yellow spots and removed his power to change shape, also causing brain damage that lowered his intelligence. This made him so volatile and unpredictable his hosts threw him out. His only living now was with a freak show. That's how he came to exhibit Noel Edmonds on Saturday evening television.
