Rusty and Lenny are the (former) secondary antagonists of the Adventures of Alvin and the Chipmunks episode "Chipmunk See, Chipmunk Do," in which they serve Troy as his henchmen. They have a brotherly relationship, despite both being somewhat dim-witted. In the end, they reform after revealing they never had anything personal against chipmunks, as well as frustration over Troy's tyranny.

Rusty is a Red Australian Shepherd and Lenny is a German Shepherd.

They make their final appearance in the series finale Christmas episode as the anti-heroes. Troy manages to manipulate them into re-serving him and his new personal sidekick, who is as evil as Troy. In the end, Rusty and Lenny realize their mistake and fully reform by helping the Chipmunks and the Chipettes defeat Troy, becoming extremely close with Theodore and Eleanor.

Rusty and Lenny are set to appear in the upcoming Chipmunks sequel as supporting protagonists.

Rusty is voiced by Donald Faison and Lenny is voiced by Zach Braff.


  • Despite being friends with the Chipmunks and the Chipettes, Rusty and Lenny are the closest with Theodore and Eleanor.
