Harry the Hippo
I would like to introduce to you Harry the Hippo. Harry is a radio controlled animatronic hippo. I control Harry out of sight and from behind my back to cycle his trike around whilst interacting with the public via a wireless microphone and earpiece.
The voice is modified to a child friendly tone and Harry has many built in mp3 files which can be activated at my control which brings a very comical aspect to the character. He also has a normal looking flower attached to his dungarees which has a concealed water squirter at the push of a button.
