2. A Donor

There's chaos at the Arnolfini Research Laboratory of St Dunstan's University when it emerges that Cara has stored several boxes of strawberry ice-lollies and some crispy pancakes in the cryogenics pod.

The Lab Rats have no choice but to defrost its occupant, Sir Andrew Chother, who was frozen because he's the most irritating man in the world and it just seemed the best thing to do. Now they have to keep him out of the way during a surprise inspection.

3. A Protest

The lab is surrounded by protesters hurling eggs and threats. The Dean is too busy selling the eggs as well as doing a roaring trade in several varieties of Dutch cake to help. And the best thing to be said of Cara's attempt to solve the security problem is that it's slightly less risky or blood-thirsty than either the Prof's or Brian's.

In the meantime, Joan Armatrading is taking part in an anti-Arnolfini Live Aid-style event in the college grounds. Can Alex manage to stop accidentally offending the hordes before they storm the place?

The Professor and Brian are stuck in the loft awaiting the arrival of a messenger pigeon. While there, they accidentally send the university's weather system haywire, sending floods, fog and baking heat through the corridors. This then makes it difficult for a reluctant Alex to help his dad - one of the university's historians - answer the question: has he really found the missing diary of Captain Scott?
