Wagga Wagga

Wagga Wagga is a town that was last seen in Episode 10: Wagga Wagga.

History
Wagga Wagga was once a town inhabited by puppies who were not yet adopted. The town was usually peaceful until Captain Slaughter kidnaps all the citizens and smashed their homes. Only a few dogs, including Cooler, Howler, and Penelope escaped from Wagga Wagga. The town is now the site of Katrina Stoneheart's fur factory while the former citizens of Wagga Wagga are prisoners. The citizens of Wagga Wagga are then rescued by the Pound Puppies.

Cooler's Cafe
As Cooler stated, he used to be the owner of his own cafe. Howler was the leader of a band and Penelope was the star singer. This cafe is presumably destroyed by Captain Slaughter.
