  • Both twins cry for the first time in Twin Time.
  • In their second sinking episode, the hurricane that hit Rockoland is known as Hurricane Ganryu. It is named after a sumo wrestler from the Tekken series of video games, which never hits the real world.
  • Like Josie and Emily, the twins lack a best friend; though, unlike Josie and like Emily, they do own a Sinkinator which is given to them by Meteor in Enter Eileen.
  • The Olsen twins are:
    • The only girls who has multiple imitations done by Krusha.
      • Their first imitation originates from their Hawaiian beach party, their second imitation is taken from their sleepover party, their third imitation is taken from their costume party, and their fourth imitation is taken from their birthday party.
    • The only formerly recurring little girls whose Sinkinator isn't given to them as a gift from Stone Buddy or Meteorite. They instead get their Sinkinator as a gift from Meteor.
    • The only major girls who have a Sinkinator that doesn't look like a metal detector. It instead looks like a walking cane used by elderly people.
