to get the gears you go to malkt then you go left, left, left, up, right, right, down,
down.you have to get the gears first, take them to the studio wait about 2 weeks (in game
time) them the person from the studio will visit your ranch, he (or she I cant tell) will
tell you he put the pieces together.

now go back to malkt, to get the head you go up, right, up, right, right, up, right, up,
up. get the head and take it to the studio then the rest explains itself.

hope i helped :)
