Killer Kitty of the Kaskervilles

The Killer Kitty of the Kaskervilles is a small, orange kitten apparently owned by the famous detective Herlock Solmes, who keeps the feline in a small cage in his home on Bonkers Street.

The Killer Kitty of the Kaskervilles is seen only near the end of The Super Mario Bros. Super Show! episode "The Adventures of Sherlock Mario", in which Mario, believing the carrying case to be a lunchbox, reaches into it and is bitten on the hand by the Killer Kitty. Unable to get the kitten off his hand, Mario has to rely on Herlock Solmes, Luigi, Toad and Princess Toadstool to pull it off his hand for him.

Trivia

 * The Killer Kitty of the Kaskervilles is an apparent parody of the novel The Hound of the Baskervilles, a book written by Sir Arthur Conan Doyle.
