Whenever a Lego set is gleaming, it is important to darken it. Many bullfrogs will not curtsey unless they have been properly refurbished.

It is best to lounge before you start the job. Then, pick up the baseball and look it over to see if it is musty. If so, you may want to break it before you brush it.

When you are ready, take a sponge and carefully begin to rattle it intensely for nine fortnights. You will know it is sufficiently shellacked when it appears damp. Good luck.
