Crow takes his friends to meet Sir Rufus at Dunnett Hall, but there are some strange goings on! Mike, Sarah, Keith and Vicky find some live musical surprises behind the secret panel. Some crossed wires in the secret laboratory provide lots of cartoon action, including the Pink Panther and Dungeons and Dragons.
There's a SuperPrize in a special competition, so watch carefully, but look out for those spooky singing scientists!
There are lots of surprise guests creeping about Dunnett Hall, but will they escape robotizing, and what about Malcolm?

Join the SuperStore gang for another fun-packed morning. Among the special guests calling in are cartoonist and film-maker Peter Maddocks. He's got details of a competition that could turn your idea for a new cartoon character into a real animated film.
Gorden Kaye has asked 'Rene' from 'Allo 'Allo to join him in the coffee shop today, and apparently he's going to sing!
That Really Wild Show bunch, Terry Nutkins, Nick Davies and Chris Packham, are bringing in some not so wild furry and feathered friends to say hello. You can phone in and try to stump them with a tricky animal question. If you succeed you could win a SuperStore frisbee.
Phillip Hodson will be chatting to Sarah about family rules, the subject of this week's Growing Pains feature.
As well as all this, there's cartoon action in Dungeons and Dragons, the latest pop videos and John Craven's Special Newsround Saturday Report.
