The "Gordian Knot replica" was a replica of the Gordian Knot of legend made by Phineas and Ferb so that they and their friends could replicate it. They managed to make a few knots in the replica, but they got some trouble when they had difficulty in trying to untie it.

Later, thanks to one of Doofenshmirtz's latest inator, Candace managed to eat the whole replica singlehandely, leaving no trace behind.
