Doraemon has a lot of human-like qualities. For instance, he loves to eat Dorayaki, which are "buns" that are like a kind of sweet pancake dough which is used like bread to 'sandwich' the anko (sweet bean paste) in between. (I tried it in Hong Kong and it tastes really good!!)
Doraemon has a fourth dimensional pocket that links to the 22nd century. He can put almost anything in there and pull lots of weird gadgets out! He often uses the gadgets to save Nobita, but Nobita ends up misusing the gadgets and getting himself into more trouble.
