-Rotating Spring, I can't describe it but it's not like a suspension block with a swivel joint. It's more like those toy cars you wind up. (Photo #1)
-Pre-Extended Slider, Slider that's already been extended.
-Multiple Keys for a single object.
-Automatic for everything, Piston that'll extend as soon as the level starts, Steering Hinge that'll bend to the right degree as soon as the level starts.
-Straight Teeth, Like the Cog but not circly. (Photo #2)
-Freezable Unpowered Wheels, The Cogs can freeze why not the wheels?
-Freezable Small Wheel.
-Magnets, Opposites attract, Not Opposites repel.
-Ropes with physics, have you seen the physics on the chains in Breath of the Wild? I want something as good as that.
-Erect Contractable Spring, Contractable Spring but doesn't collapse.
-Bomb with a fuse, add a little a fire, then get the HELL AWAY FROM IT!!!!
-Unpowered Flying Block, like a normal Flying Block but with no motor.
-Inverted Cog, like a normal cog but with the teeth on this inside, and maybe the outside.
