The doctors reveal what happens when you get diarrhoea, Dr Xand gets his skates on when he meets Alexia and Kloe from CBBC's Ice Stars to investigate how they spin without getting dizzy, and there's a hidden camera experiment. Meanwhile, the ouch-mobile is open for more medical mysteries, and in accident and emergency one patient needs surgery for a broken arm and another gets help with a painful toe.
