While searching for an obscure book for Gaius in the library, Merlin accidentally triggers a hidden room and discovers an old box which when opened releases a goblin who proceeds to take over Gaius' body and cause havoc around the castle. This episode is a departure from most, in that it contains a much higher level of plain fun, frolics and silly entertainment. Richard Wilson as Gaius gets to throw off his usual fatherly figure, and indulge in some truly childish stuff which he pulls off with flair. The writers clearly decided to just kick back and let off some steam - although the scene between Gaius and Lady Morgana reminds the audience of the continuing plot, and some of the antics Gaius gets up to are clever and original.
