Nintendo Twins (任天堂 ツインス, 1971)

In the early 1970s, Nintendo was still going in all sorts of directions commercially. They even (briefly) tried the baby and toddler market with the Mamaberica stroller and the Twins. Japan was still going through the post-war baby boom, so this must have been a lucrative but crowded market. Nintendo tried to get a piece of that pie through innovative product design.

The Nintendo Twins (ツインス) is a plastic, multifunctional baby-seat-child-seesaw contraption.

It is the biggest "toy" Nintendo released.
