A dumpty is a sweet and calm animal (most likely a dog but could be a rabbit or a gremlin in disguise). Dumptys are the sweetest animals in the world and they never bite, bark, or shred things because they are so calm. Dumptys love their master and are protective. They protect the house during the week when they sleep in the living room and they get rewarded with cuddle time on weekends for their good work.
Look at that sweet little dumpty! She sure does love her master.
