To win a dog show, and later, to sniff out magma.
Originally made by Crazy Chicken Lady in order to win the dog show, it was then upgraded by having a Logic Diamond place inside of it without the owner's consent. This dog suddenly burnt up when the logic diamond overloaded its system. Later, after the dog was rebuilt, it was upgraded again, this time with artificial mucus, in order to sniff out the magma pocket accidently formed under Eureka.
It was presumably given back to its owner, but did not win the dog show, the prize having gone to Fargo's dog.
