When the Browns find Paddington lying on the lawn, unable to remember where he is or even what the word "bun" stands for, they immediately realise something is seriously wrong and send for an ambulance.
For a while even the doctors are baffled, but gradually all is revealed. One thing is certain, the staff have never had to deal with a patient quite like Paddington before, but then it is his first time in hospital. Both sides agree that they have learned a lot from the experience!
