Lambo is a large sheep who is the main antagonist of the 101 Dalmatians: The Series episode "On the Lamb".
Lambo is first heard about when Cadpig, Rolly and Spot pick up a message on the barking chain from Kelly, a sheepdog with a fear of sheep (who previously appeared in "Tic Track Toe"). Lucky assumes that it is just a search for a smaller lamb and gets annoyed when the Bark Brigade assigns him, Cadpig, Rolly and Spot, along with Lt. Pug, to find and return the lamb.
When the Dalmatians and Lt. Pug begin searching, they are led into an alley. When Lt. Pug suddenly realizes that the alley was a trap, Lambo then reveals himself and proclaims how he is not going back to the flock. Despite what Spot suggests, Lucky is now even more determined to capture Lambo.
Lucky first sets up a trap in the Gruteley Garden Nursery, figuring that Lambo would get hungry and try to eat the plants there. The Dalmatians try to trap him with a net, but he is able to shake the net off him and trap the Dalmatians under a birdbath.
Lucky's next plan is to lure Lambo into a toy store, by playing "May Had a Little Lamb" on a music box, something which Lambo finds demeaning. Lambo is then lassoed, and the Dalmatians are pulled around Gruteley before Lambo shakes off Cadpig, Rolly and Spot, but manages to capture Lucky.
With Lucky as his hostage now, Lambo tapes Lucky up. Cadpig then arrives to negotiate, but Lambo refuses to negotiate and dares Cadpig to talk herself blue in the face, which Cadpig does. Many hours later, Lambo is driven mad by Cadpig and surrenders just to get her to stop talking.
With Lucky rescued, Cadpig, Rolly and Spot return Lambo to Kelly.
- Lambo is literally the black sheep of the flock, which is also an idiom used to describe a disreputable member of a group.
- Lambo's appearance and name is an homage to Sylvester Stallone's portrayal of Rambo.
