Silverado Brothers

Sneaky and Speedy Silverado, the Silverado Brothers, are a pair of silver bandits from Sheriff Callie's Wild West who serve as the primary antagonists of the episode "Blazing Skaters". They only strike during the winter and manage to escape without being seen (their photo on the wanted posters is so blurry due to them being fast).

Background
Sheriff Callie first gets word of the bandits' thievery at the town of Junctionville. When she investigates, she finds that everything silver has already been taken -- and the only left behind strange tracks. Callie follows the trail back to Nice and Friendly Corners and deduces they will be after the trophy for the Silver Skates Ice Contest. She spots Sneaky and Speedy in the audience, and when they catch sight of her, they split. They nab the Silver Skates trophy, and also grab Callie's ice skates so she can't pursue them on the slippery ice. But Abigail Crane is still wearing her skates, and goes to catch up with Deputy Peck, who then notices Sneaky and Speedy with the trophy. Abigail and Peck decide to pair up to stop the bandits, and corner them by using the Quadruple Lasso Loop. They skate a figure eight around the bandits so fast that they end up cutting the surrounding ice, trapping the brothers on a pair of ice floes. Callie then lassoes the Silverado Brothers and then puts them "on ice".
