Description
The crop turns light blue and gives off snowflakes with a soft blue mist around it.
You can get this mutation during the Route Runner Admin Event.
Since it’s an admin event, only game admins can spawn it.
When the event is triggered, a sky-colored tornado forms in the server, and a giant monkey appears that enters gardens and mutates the crops it touches.

This mutation gives a massive x50 multiplier to any crop it affects.
That means it boosts the fruit’s selling price by 50 times.
For example, a 1.9 kg peach normally sells for 271 Sheckles. With this mutation, it jumps to 13,550 Sheckles.
Visually, the mutated crop appears light blue, emits snowflakes, and is surrounded by a soft blue mist.
