I bought my daughter a leap pad 2 and I am still a little bit confused in how to get games into it. My daughter wants me to buy her the Tangled game but I do not know how to. Do I have to go into a shop and buy the cartridge for the game or do I download it? If it is only downloaded into the leap pad2, isn't there a chance that my daughter can accidentally erase it? I have Google'd throughout but not too sure how to go round it.
