Part 5 of 6 of the children's drama from 1990. Billy tries to tell his family about the mysterious Alphonso Bonzo, but they are sceptical. That is until Alphonso turns up unexpectedly at the house and proceeds to ingratiate himself into the family, while turning his attention to Billy's teenage sister Linda. And when Alphonso uses his powers to meddle with the television set, he offers to bring over his own TV set as a replacement. But his Milanese TV set has some very peculiar side effects, which Billy is soon to discover. Final episode hopefully tomorrow.
