Lego Sliding Panel Compartment

here is what seems to be a sliding puzzle but once you move the right panel your prize awaits

for this you will need 8 4x4 studded plates and 8 2x2 smooth or one studed plate. you will also need pieces for boardering the 2x2s.

im fairly certain that you can figure this out easily but for the part with the whole in it, well see the next step.

this should be a fairly simple step.

this step depends on what you want your friend, sibling, or whoever it is, to find. for this im using a lego barrel. hope you enjoy.
