2x11 - Curious George

George is pretty mad at Hundley who will simply not let him play in the lobby and wishes Hundley could be more like him. One day though, he notices that Hundley is barking loudly and acting bouncy and playful, much to his wish! He then notices that Hundley seems to go back and forth between acting bouncy and playful, and acting like his normal self. Realizing that something is not normal about Hundley's split personality, he tries to figure out what is going on.
