Trading only
The Mermicorn is a legendary pet from the Summer Festival (2025) in Adopt Me. It arrived on July 4, 2025 as a 1,000 Robux pet and is no longer sold. Today the only way to own one is to trade for it, as a Normal, Neon or Mega Neon, with or without Fly and Ride.
Mermicorn
Values are in Sharks (1 Shark = a Shark with no potion), the same unit as our Adopt Me trade calculator, and they update often. D = no potion, F = Fly, R = Ride, N = Neon, M = Mega Neon.
