Sylvester Sneekly is the guardian of Penelope Pitstop, yet he desires her vast fortune she is entitled to. He intends to have her dead so he will become the only reamaing claimant of the fortune. Of course to protect his identity, he carries out his plans and traps as a sadistic, sneeky, foul, master of disguse villian known as the Hooded Claw. He does have a foul, childish temper, especially shown when his plans are foiled by Penelope, The Ant Hill Mob or even his own blundering henchmen, the Bully Brothers.
The Hooded Claw is highly devious and brilliant in his fantastic traps he conducts. He is a master of disguise, able to change merely by twirls and quick moves, he once even managed to turn himself into Chuggaboom's spare tyre.
Both the Hooded Claw and Sylvester Sneekly were performed by Paul Lynde, and currently by Tom Kenny, although he wanted to be uncredited.
- In contrast to his name (as seen in the photo above) the Hooded Claw does not wear a hood, or have a claw at all.
- He actually, surprisingly twice transformed between his two identies in front of Penelope. The first time wasn't as obvious as he was bending down behind a desk, but she doesn't believe it to be true the second time, declaring it an insult to he devoted guardian.
- In "The Pied Piper of Peanut Creek" storybook by Badger Books and Studio publications, the Hooded Claw becomes a parody of the Pied Piper and lures children and Penelope into an old mine, attempting to bury them inside. But he is foiled by the Ant Hill Mob, while Penelope rushes out to declare the children found a seal of gold inside, to the Hooded Claws distaste.
- Clyde is suspicious of Sneekly is the same book.
