The Nugget in a Biscuit is an Expert Mode-exclusive pet summoning item obtained from the Treasure Bag dropped by Jungle Dragon, Yharon. It summons a small Yharon nugget to follow the player.
- The item's name is a reference to the song "NUGGET in a BISCUIT!!" by Youtuber Tobuscus.
- The appearance of the Jungle Nugget is based on the minion summoned by Yharon's Kindle Staff.
- The name also references an inside joke in the Calamity community involving how the minion resembles a chicken nugget.
