The House of Acorn was a version of the House of Acorn from a possible future timeline of Mobius. Having defeated their version of Dr. Robotnik, the House of Acorn ruled peacefully over Mobius for some time, even sending NICOLE back in time to Sally Acorn after her counterpart in this reality had lost her own computer. Sadly, the House of Acorn's rule-along with their lives-were cut tragically short with the return of their Robotnik, who would later be known as Dr. Eggman.
