Finding the Knuckles Skin
To get the Knuckles skin in Sonic Speed Simulator, you will need to unlock the Emerald Hill level and locate the Knuckles card on the map. Once you do, you will then be able to equip the skin and run around as Knuckles!
The first step towards getting to the Emerald Hill world is to complete the Lost Valley Obby. This is an easy to do stage where you will just jump across some cliffs. You shouldn’t need to have too much speed at this point to finish it, but you do need to be level 25. The obby is located in the spawn world up a hill.

Now comes the harder part, you will need to reach level 50. You need to run around collecting orbs, coins, and jumping through XP hoops to earn levels. Keep this up all the way until you finally reach 50. Once you have done so, you will need to rebirth your character. This exchanges your current level and speed for new rewards, including +7,000 Coins, higher max level, and a 2x XP multiplier.
Unfortunately, once you rebirth you will need to level up your character again to gain speed. However, with the additional XP multiplier you can do it pretty fast. Once you reach level 25 again, head to the Lost Valley Obby and reach the Lost Valley area. You will probably want to level up some more, at least until you reach 40. Then you can jump into the Emerald Hill Obby and complete it to unlock Emerald Hill.

Head over to what is essentially the middle of the map and look for the wooden tower with a bumper on it. Jump towards it and use your jump attack to bounce off of it.

Once you stop bouncing around, continue towards the next set of bumpers. You will eventually see a Chao + Trails vendor and a curved road. Go across the curved road towards the platform with a ramp. Use the ramp to get to the final platform, where you will be able to collect Knuckles!
