The Diamond Unicorn is a legendary pet in Adopt Me! that was added on March 20, 2020, along with the Star Rewards update. It can be hatched out of a Diamond Egg. The Diamond Egg is extremely difficult to obtain and requires players to maintain a very large streak, hence making it one of the hardest obtainable pets in the game. It takes about 1 year and 3 months to obtain a Diamond Egg. The other two pets that can be obtained from the Diamond Egg are the Diamond Dragon and Diamond Griffin. You can obtain a Diamond Unicorn by hatching one out of a Diamond Egg or through trading.
The Diamond Unicorn is a re-coloration of the Unicorn that has a shiny looking blue body, a golden horn, a golden mane, and a golden tail.
The Neon version of the Diamond Unicorn glows bright yellow/gold on its mane, horn, and tail. This version's color can be different in the day than it is at night.
Mega Neon Appearance
The Mega Neon Diamond Unicorn glows in the same spots as the Neon Diamond Unicorn would, but instead of glowing bright yellow/gold, the Mega Neon Diamond Unicorn glows in four different colors— white, blue, teal, and light yellow.
- A Neon Diamond Unicorn once got into the game, even though the owners of Adopt Me! said that it was not supposed to be in the game until December 2020. The person could have had a very high daily streak (600-700) days and could have obtained extra Diamond Unicorns from other players with high login streaks, but it was most likely a hack. The player was banned from Adopt Me!.
- The creators of Adopt Me! joined an Adopt Me! server and showed people the most popular pets in the game, including the Mega Neon Diamond Unicorn.
