At Daddy's work there is a Halloween party. We were really excited to go! He doesn't know how to say "trick-or-treat" yet, but he does understand chocolate. In order to get the message across he growls and smiles (get it? "growls-or-smiles")in his lion costume. So far no one has been able to resist him.
Theravance also had inflatable bouncy rooms. He tried that out too!
