There is a short post-credits sequence, of sorts, in which the animated Gnomes form a 'Sherlock Holmes' logo. This logo is then teased by the animated Moriarty, who is then smashed by the magnifying glass of the logo and says "I hate you, Sherlock Gnomes."
No gnomes were harmed in the making of this motion picture... well, okay, maybe there were a couple.
There are various gnome animations in a cartoon-like fashion throughout the entire length of the credits of Sherlock Gnomes.
