I vaguely remember this, I was Worzel Gummidge obsessed as a kid. Do you remember a collection of mystery booklets from Frosties in the 80s dealing with subjects like the supernatural? Each mystery featured Tony the Tiger's theory, in the case of the Mary Celeste he theorised the crew had run out of Frosties and were rowing to shore to stock up when they were swept away in a storm.
@@cerealmad I think there was another one with an illustration of Banquo's ghost though it may have been from something else around the same time, too long ago to remember now!
