A glitch from the original The Legend of Zelda: Ocarina of Time persists in the Nintendo Switch remake, allowing players to collect Gold Skulltula Tokens infinitely from a single enemy.
The glitch works in a grotto outside Hyrule Castle accessed by playing the Song of Storms. A Gold Skulltula behind a bombable wall can be defeated with a boomerang and its token collected. If the token is collected while exiting the room via the flower elevator, the Skulltula respawns when the grotto is reentered.
Reddit user Wrong-Kangaroo-4352 first noted the glitch nearly a week ago. User theletter454 later explained the mechanics. Initially, the Skulltula did not reappear after collection, leading theletter454 to assume it had been patched. After finishing the game and noticing 1 percent completion missing, they returned to find the Skulltula back in place.
Theletter454 determined that the loading zones must be completely reset for the enemy to regenerate. This requires swapping between adult and child Link or warping to areas with different loading zones, such as Lake Hylia. The process is more time-consuming than the original glitch but achieves the same result.
The game's counter prevents collecting more than 101 Skulltula Tokens total. Comments note that Nintendo developers, including Satoru Iwata, deliberately left certain bugs in the 2011 3DS remake because staff considered them fun and part of the original experience.
