Jack

Jack is a male mouse character who first appeared in JumpStart Kindergarten (1998).

Appearance
In JumpStart Kindergarten (1998) and JumpStart Math for Kindergartners, Jack has sandy brown fur with a peach-colored face and a light brown belly. He wears green pants and has a light peach-colored sack that is slung over his shoulder. He is an adult character, although unlike Hopsalot who is the same size as a human, Jack is roughly the size of a real mouse.

In JumpStart Kindergarten: Why Did the Bus Stop? and JumpStart Learning Games: Phonics, Jack has light gray fur, a darker gray tuft of hair on his forehead, and a white snout and belly. He wears blue pants held up by a single red strap held over his shoulder. His age has been changed from that of an adult to a kindergartner, and he is the size of a human child.

Personality
Jack is straightforward and sensible, though not humorless. He can sometimes get slightly annoyed at Roquefort, but they are still good friends. He acts more childlike in JumpStart Learning Games: Phonics and JumpStart Kindergarten: Why Did the Bus Stop?, as his decreased age might suggest.

Trivia

 * Since Jack's friend Roquefort is named after a type of cheese, Jack's name may also come from a kind of cheese. There is a kind of cheese called 'Monterey Jack', also sometimes referred to as 'Jack cheese', which could be the basis for Jack's name.
