Mr. Wink and Mr. Fibb were voiced by Tom Kenny and Dee Bradley Baker, respectively.
They are almost always seen sitting next to each other and have an alternating speech pattern, often asking rhetorical questions to each other and addressing the other by name at the end of each sentence.
Mr. Wink has a large brown tuft of hair that covers his eyes and has a pair of buffalo horns protruding out of it, while Mr. Fibb has walrus tusks and and very large, flipper-like webbed hands. No reason for the duo's bizarre appearance is ever given.
Mr. Wink and Mr. Fibb were the first villains to appear in the series, being the antagonists of the pilot episode,No P in which they are the lifeguards of a local pool and are not letting children swim in it, due to their belief that kids will "dirty up the pool" (completely oblivious to the pool filters, apparently). In Operation: C.O.W.G.I.R.L it is revealed that as children they were members of The Cowboy Kids Club, another group of children who fought adults. Their first names (John and Timothy, respectively) are also revealed in this episode. They also have many appearances alongside the other villains.
- Mr. Wink and Mr. Fibb are based of the two James Bond villains Mr. Wint and Mr. Kidd from the movie Diamonds Are Forever.
