A Matter of Loaf and Death
Twelve bakers, including Bob,  are murdered by a serial killer named Piella Bakewell.   Wallace and Gromit save Piella and her poodle,  Fluffles,  when the brakes on their bicycle fail,  and they fall.   Gromit finds out there is no problem with their brakes,  but he and Wallace are smitten.  They and Piella perform a whirldwind romance.  But Gromit is angered when Piella redecorates  the house.   After Piella tricks Wallace into her thinking after she bit her own arm,  Gromit is muzzled and chained up.  He watches helplessly as Piella tries to push Wallace to his demise,  but he is saved by Gromit,  accidentally causing Piella to be struck by a bag of flour.  After she makes an angry outburst that she hates bakers,  Piella drops by the next day to apologize with a cake.
