area 2 you will find a bounty hunter panel
activate it and get the power brick!
at the area were you fight off those 2 guard things theres a storm troop panel
go in it and set up the tiles 1 by 1 or maybe it was just forcing those things!
first go to the last area and go in a R2D2 panel and you will see 3 tubes
the easiest way to do it is change into a high jump chaecter and jump into the middle one
all you have to do is force 8 squares and it will apear in the emporers chair!
oh this is also the easiest one in the game and you can even do it in story!
at the top right corner theres a hidden tunnel
go in there and get it
you have to destroy all of the trash cans in one tiny area
force the cans to take the stuff and build a panel and it will bring you to a door and boom you got it!
