Mutation Spray Merchant Trivia
- The merchant was originally named “Uncle Sam” during his first appearance, likely by mistake, and was later correctly renamed to Mac.
- Earlier versions of the shop offered a Disco Mutation Spray, but it was removed after player feedback since many felt the Disco mutation should remain rare and exclusive.
- A small glitch occurred if players tried to open the shop menu right before Mac despawned, showing a “Restocking” message instead of allowing purchases.
- Just like the Sprinkler Merchant, Mac’s shop had uniform pricing, with all sprays costing the same amount.
- After Update 1.24.0, the Mutation Spray Merchant was officially retired from the merchant rotation and is no longer available in the game.
