Fisher-Price Great Adventures Castle (1994)
This playset includes the grey castle on a green base, one black king and four black knights, one gold king and four gold knights, three grey boulders, and a round table. Each of the four different knights has a unique weapon, and when you push down on the king's heads, their weapon arm swings with a chopping motion. The castle features a flip down cannon on the front to shoot boulders, a catapult on the back left turret for launching boulders, a flip out hiding place on the left front turret, and a collapsing floor on the right turret which is hollow and serves as a dungeon with a gate on the bottom. The right turret has Fisher Price printed in blue near the top. A lever inside allows you to raise and lower the drawbridge and makes a clicking sound when you do so.
