Please can somebody help me it's been driving me mad for ages... I've beat the gym leader in Cerulean City and I've seen the manager about the stolen item, as I was on my way back to the gym I saw a team rocket member he told me "if you beat me I will tell you were the item is" I beat him and he told me it's in the gym hidden !
I CANNOT FIND THIS ANYWHERE!!!
What do you have to use in order to get the item ?
