One of the entries in this series was an episode entitled “Mr Swlabr,” about a boy with some real jerky family members.
He gets something out of a cereal box, adds water, and it turns into some disgusting (talking) reptilian critter called “Mr Swlabr,” who befriends the boy, and protects him from his jerky step-father.
Maybe the writer was a Cream fan? I thought he picked the name out of thin air since the critter “slobbered” a lot (or so I seem to recall).
And I bet that you thought that by the subject it had nothing to do with the mailbag!
