Patti and Jimmy were characters from the
Sanrio family. They were just a little boy and girl (no
cats!), who were always doing something involving things
golf,
tennis, or
polo.
Discontinued in the U.S. suddenly in the
80's, they are still available from Sanrio Japan. They can be seen in the Sanrio
video game for the
playstation,
Hello Kitty Cube Frenzy.
