(super sonic required) If you want to get twinkle circut with tails,knuckles,gamma go to the left of the huge building you will see a grass area and a cart pass hold it and go to twinkle circut normally it will last for ever!!!
I thought that you would have been looking for the silver statue for Knuckles. Well, I have got the location .For getting it you must go to a nearby cave from the starting of the jungle. First climb down the ladder. Then go to the path on the right . Then cross the a shallow river and walk straight. You"ll either end up near ancient building or a cave. If it is a cave then go inside. You will find that there is a revolving golden circle going up and down . Go to it's centre and start digging.You will see the silver statue.
If you want to get mission 60 you need to get to the mystic ruins station .There walk to the front of the train, if you aren't getting my point,go to the dark gate from where you entered mystic ruins go to the train and bravo! You got it.
How to complete it: go to the Ice cap stage. There go to the skull of the dinosaur.You will see a flag in it.You can enter it by passing through it's eye.
Hope I helped
And don't get cross if I don't because it is my first submission.
