As you can see from the packaging, the Toypedo is a hand-launched projectile meant to be inserted into young boys' mouths that can travel up to 40 feet underwater, just like a "nuclear submarine."

Cool, so we seem to be simultaneously encouraging fellatio (not that there's anything wrong with that between consenting adults) and a casual acceptance of nuclear war ("Johnny, go play with Red October."). Alllllllllrighty!
