Role in the film
In the movie, Toby is the dog of Sherlock Holmes, who lives above Basil of Baker Street. Although he is Holmes' dog, he assists Basil solve cases, too, and is perhaps Basil's most loyal friend (next to Dr. Dawson). When Basil, Olivia, and Dr, Dawson find Toby, Olivia and Dr. Dawson both ask who Toby is and then he appears as Basil calls him. Basil politely introduces Dr. Dawson to Toby first, to which Toby sniffs Dawson and snarls at him, but Basil tells Toby to back down. Then, all of a sudden, Toby smells Olivia and takes a good liking to her and she gives him one of Mrs. Judson's cheese crumpets to eat, chamomile tea to drink and she also rubs his belly at once. Then, in the meantime, she drinks the tea only to fall asleep on his belly after while trying to rub his belly. Then, Basil asks Toby to sniff out Fidget the bat's hat in order to find Fidget, who will lead them to find Olivia's father, who was kidnapped by Fidget earlier in the film. After Toby sniffs out Fidget, Basil, Dr. Dawson and Olivia climb on him and he takes them to a toy shop in town, where Fidget is stealing stuff for his boss, Professor Ratigan. When they show up, Toby's howl warns Fidget who hides. Toby permits Basil and Olivia to get off, but he snarls at Dr. Dawson and sneezes, causing Dawson to tumble into Basil. Then, Basil tells Toby to sit, but he remains standing; however, when Olivia tells Toby to sit, Toby listens and sits. Later on, as Fidget tries to get away out the door with Olivia in his bag, Toby growls at him, but Fidget manages to take another exit. Shortly, Toby takes Basil and Dawson back to Baker Street. Later on, when Basil and Dawson discover that Fidget has drank beer from a pub where the sewer connects to the waterfront, Toby takes them to the waterfront and Basil tells him to stay put to (which he does). After getting away from Ratigan's traps and rescuing Olivia, Basil calls for Toby to take them to Buckingham Palace, where Ratigan and his minions are trying to slaughter the Queen and rule the kingdom. When they show up, Basil, Dawson and Olivia manage to rescue the Queen Mouse from being fed to Ratigan's cat, Felicia, and Toby manages to chase Felicia away. Toby tries to catch Felicia, but she manages to get away through a fence, where she is attacked by the royal guard dogs. After the case is solved and Ratigan and his minions are defeated, Toby is seen listening to Basil's next case at long last, in which a lady mouse has lost her ring.
