Blue And Who? (EP.243)
Blue is an Australian Shepherd owned by Stacy in Dogcraft.
In preperation for the second creeper war, Stacy went through the nether to find a jungle so she could form an army of cats. In the process, she saw a bunch of wild Australian Shepherds, a breed which she didn't have yet.
After the war ended, Stacy went back to the Shepherds, where she rescued two of them, the first being Blue, which she named after a viewer's comment.
