Rules of Frogger
You are a frog. Your task is simple: hop across a busy highway, dodging cars and trucks who come out of (and go back into) tunnels, until you get to the edge of a river, where you must keep yourself from drowning by crossing safely to your grotto at the top of the screen by leaping across the backs of turtles and logs.
What are the NOUNS of this description?
NOUNS = AGENTS
