Lucky is a miner pup. He saves people if they are caught in a rockslide. His buddy's are Bolt and Rocko.
Lucky will appear in "PAW Patrol vs WAP Patrol (part 4)" when he throws a rock at Ty to help the pups. He is a lot like Marshall since they both are Dalmatians and they have yellow collars.
Lucky wears green like Rocky. Both of his ears are grey.
