Click the Mouse is a character in Between the Lions. She is a computer mouse shaped like a real mouse. She is also known for narrating the pbskids.org promo at the end of every episode.
She is a very high tech mouse in the fact that she can drag and drop objects and characters into and out of books and websites. When a character needs her, they only need to call out her name (usually screaming if it's an emergency) since she doesn't mind helping others and will do what they tell her what to do.
Her only weaknesses are, being a computer mouse, she must always stay connected to a computer and that she is vulnerable to computer viruses, as shown in one episode.
