Beat all nine stages in the new Sonic's Green Hill event and get Sonic in Cookie Run Kingdom with the help of this guide.

Devsisters and Sega have joined forces and introduced two new and very special cookies in Cookie Run Kingdom: Sonic the Hedgehog and Tails. The new crossover event "Sonic's Green Hill" will take place from September 17 to October 16, 2021.

Our guide will provide you with tips and tricks on how to get Sonic in Cookie Run Kingdom and complete this awesome event. You will learn about all the stages of the event and how to beat them.

How to Unlock Sonic in Cookie Run Kingdom

Sonic and Tails cookies can be unlocked through Lucky Item Boxes that contain various rewards. Each opening of a box will cost you a 1,000 rings, and since there are 30 rewards in total, you will need 30,000 rings to unlock all Lucky Item Boxes rewards.

The rewards are completely random, so you could get Sonic on your first opening or on your last one. In either case you can play Sonic's Green Hill event as many times as you want, since it is the only event in Cookie Run Kingdom that allows you to earn rings in unlimited amounts.

Preparation

You will have to pay a certain amount of Power Sneakers for each of the nine stages in Sonic's Green Hill event. The only way to get Power Sneakers is to wait. You get one Power Sneaker per 30 minutes of being logged into the game. You can use this time to play other missions and upgrade your cookies.

Once you save up enough Power Sneakers for each stage, you will have to assemble a team of five cookies. Here are the best cookies for the Sonic's Green Hill event:

  • Sea Fairy Cookie
  • Vampire Cookie
  • Squid Ink Cookie
  • Sorbet Shark Cookie
  • Licorice Cookie

You can also use treasure buffs to help your team deal with bosses, such as:

  • Old Pilgrim's Scroll (increases attack power of your team)
  • Priestess Cookie's Paper Charm (debuffs all enemies)

Stage 1

  • Power Sneakers: 20

This stage is totally straightforward. Collect your coins and rings, and at the end you face Doctor Eggman with 30,000 HP, who uses Laser Beam. Attack him as soon as he appears, and you should beat him in no time.

Rewards for Stage 1 are:

  • 500x Rings
  • 100x EXP Star Jelly Lv.2
  • 5x Skill Powders

Stage 2

  • Power Sneakers: 20

In the second stage you have to overcome some spikes as jumping obstacles, and at the end you face Doctor Eggman again with 46,580 HP. Apply the same strategy and he should go down fast.

Rewards for Stage 2 are:

  • 800x Rings
  • 120x EXP Star Jelly Lv.2
  • 5x Skill Powders

Stage 3

  • Power Sneakers: 20

This time you'll be surprised by enemies unexpectedly appearing from beneath the ground, so just jump over them. The boss at the end will have 65,540 HP and shield protection. Break the shields first, using Priestess Cookie's Paper Charm treasure, and then attack the boss himself.

Rewards for Stage 3 are:

  • 1,000x Rings
  • 80x EXP Star Jelly Lv.3
  • 5x Skill Powders

Stage 4

  • Power Sneakers: 22

Doctor Eggman will have 92,240 HP this time, but the strategy stays the same: use your treasures to break his shields and buff your attack to keep pressuring him.

Rewards for Stage 4 are:

  • 1,000x Rings
  • 100x EXP Star Jelly Lv.3
  • 3x Skill Powders

Stage 5

  • Power Sneakers: 22

At this stage, the number of spiked obstacles increases significantly. This means that you have to be a bit slower and more careful. The boss at the end will have 136,260 HP, which is a lot but beatable.

Rewards for Stage 5 are:

  • 1,000x Rings
  • 120x EXP Star Jelly Lv.3
  • 3x Skill Powders

Stage 6

  • Power Sneakers: 23

This stage has a very long portal section that you need to run as fast as possible. There are lots of coins though, so use Ginkgoblin's Trophy Safe treasure to collect them all. The boss now has 233,080 HP and 7x Shields to break.

Rewards for Stage 6 are:

  • 1,200x Rings
  • 60x EXP Star Jelly Lv.4
  • 3x Skill Powders

Stage 7

  • Power Sneakers: 23

Starting from this stage your cookies need to be at least Level 40+, because Doctor Eggman will start doing a lot of damage and his own HP will be at 387,600 points.

Rewards for Stage 7 are:

  • 1,200x Rings
  • 80x EXP Star Jelly Lv.4
  • 2x Skill Powders

Stage 8

  • Power Sneakers: 23

Here you will face the same amount of power as at stage 7, but now the boss has nine times the shield and 449,320 HP. You can switch one of your cookies to Black Raisin cookie for this stage due to double damage.

Rewards for Stage 8 are:

  • 1,80x Rings
  • 100x EXP Star Jelly Lv.4
  • 2x Skill Powders

Rewards for Stage 9 are:

  • 2,000x Rings
  • 8x EXP Star Jelly Lv.5
  • 2x Skill Powders

Unlock Sonic and Tails

You can start opening Lucky Item Boxes as soon as you get 1,000 rings to open Sonic and Tails as one of the 30 possible rewards. Open as many as you can by completing Sonic's Green Hill stages and soon you should get this special cookie.

Alternatively, if you get the seven Chaos Emeralds of different colors from the boxes before opening Sonic and Tails, you can use them to unlock Sonic at the Miraculous Chaos Emerald menu as a guaranteed cookie.
