** Throughout Epic Yarn, the best pieces of the end of level spinners were referred to as "Gigaquads". [[spoiler: come Pokecapn's let's play of Four Swords Adventures, we get to see the true Gigaquad, a monstrously beautiful mess of four Gamecubes emulating Game Boy advances plugged into a Wii U emulating a Gamecube...]]
** Also, in Kirby 64, Medibot ended one of his episodes with the command "Destroy all ducks". Then, in Epic Yarn, Medibot and Kaz find themselves facing what they call "Hadoken Ducks" as a recurring enemy.
* MemeticMutation: In the first Dreamland stage of Epic Yarn, Kaz says "I am Prince Fluff and what is this?" [[spoiler:[[CallBack He says it again]] when they move to the yarned Dream Land.]]
