I'm going to show you how to reveal the king of rabbits! This is the achievement that I struggled with so much, when it was quite simple the whole time.
How to Reveal the King
This is all going to be done in the first level of the game, Lavender Mountains.
Within this map, there are spots where you can find rabbits. If you get too close to them, however, they will start to run away from you.
If you manage to get close enough to the rabbit and touch them, they will make a squealing noise.
Once you have tickled all of the rabbits, the achievement will be granted to you, and you can go see the King!
So you've revealed the King! But wait, there's more!
Located underneath the rabbit is a shiny rainbow-colored egg.
Go ahead and touch the egg for a little surprise!
