I am a sucker for a puppet selling me stuff and when you put that puppet in a perilous situation I cannot resist looking. That is exactly what SpaghettiOs did in the mid-eighties with their Mr. O character. He would be in trouble, which would trigger an O Alert and the kids would come running. In this classic ad he faces off against the top hat wearing Mr. Badlunch and I bet you can guess who wins in the end.
I am not sure if this is a “phantom memory”, but I seem to remember sending away for some sort of Mr. O merchandise or a t-shirt. I did a quick look online for the shirt and couldn’t find it. Maybe it was only wishful thinking.
