Beast boy would land outside of the tower as a green hawk. He would transform back to human form and stretch his arms "Ahh that was a flight.." he'd look up at the tower "woah.. now that's cool" he says getting a big grin "Wonder if there is anything fun to do around here.." he'd walk to the door and enter as well humming to a tune in his head swinging his arms and swaying his hips.
