What should I do for my cousin's birthday?

I don't know what to do for my cousins birthday, any ideas?

It really depends on what your cousin likes. Take what he/she likes and make the bday party themed after that. (or you could just do something generic.)

Invite a bunch of your cousins friends over, see if someone has a nintendo wii you could borrow or DDR they are both fun for parties. Have food, cake, ice cream etc
