This is an interactive Nintendo DS! Certain things do stuff when you click on them! (also btw this is based on my personal DS which is technically a DS lite which is an enhanced version but still its a type of DS so it counts)
btw the sounds that play when you click the d-pad, a, b, x, y, start, or select buttons are real sounds I recorded by recording the sound of me clicking that corrisponding button on my real DS. I know it's amazing right?
