There, the Littles soon learn of Augustus' ill-tempered and mean-spirited ways: He treats Henry more like a slave, and is planning on replacing his nephew's house with a shopping mall. While the creatures try to escape, Henry discovers Grandpa and Dinky, not knowing who—or what—they are. Augustus also sees them, but mistaking them for toys, grabs them from Henry and locks them in the desk drawer in his study. Here, Dinky and Grandpa discover that Augustus forged the documents in order to become Henry's legal guardian, as well as to steal and redevelop the Biggs' property.
