Cheese Obsessed Canadian Trouts

In the 4th and Semi-finale chapter of Cartoon Network Invaded, three new Canadian fish appear as new scouts. Samson tries to run them out of camp when he learns they want to steal cheese, which furthers his mistaken belief that the Canadian trout are the aliens. After the trout achieve their goal of stealing cheese, one of them states that this is the worst he's ever been treated in all of their career as professional cheese thieves. They're voiced by Carlos Alazraqui and Jeff Bennett.
