Waluigi's Rubber Ducky
- Main article: Waluigi's Rubber Ducky
Quackington first appears in SMG4: The Mario Convention!, where Tari finds him in a bargain bin.
In SMG4: The Mario Purge (Halloween 2018), a Teletubby shot an arrow at Saiko, but Tari tackled her out of the way. They were unharmed, but Quackington was impaled on the wall by the arrow. Tari mourned the loss of her toy duck, but it was cut short when Saiko tackled her out of the way of another arrow. Quackington is currently replaced by Archibald.
Archibald debuted in SMG4 Christmas 2018: The Most Important Thing in a store window. He is later delivered to Tari as a Christmas gift. Archibald was destroyed by a corrupted dead meme from the Internet Graveyard.
