The Miracle Thread is an unknown item that was apparently sought by Nintendoki as part of his original list and would have been the last item obtained by The Original Smoosh if it wasn't for the fact that they were mysteriously exiled from The Universe before they had a chance to find it. Although the purpose and significance of the Miracle Thread is currently unknown, it is apparently originally from Luna's Homeworld, seeing as this is where the Original Smoosh was seen looking for it in Luna's flashback.

According to a recent conversation between Nintendoki and two members of the Original Smoosh, Nintendoki has yet to find the Miracle Thread, though he intends to use the current Smoosh in order to do so.
