Killer Kitty of the Kaskervilles

The Killer Kitty of the Caskervilles, biting on Mario's finger.

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

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