Settling yourself into the new role of Royal Dispute Settler, your first item on the agenda concerns a young filly who happened to catch your advert in the paper and decided to seek your advice. You ask why she never asked her parents, but she explains that they're part of the problem.
Her father's birthday is coming up, apparently, and as he is an avid pool champion (six times winner of the Cue Shot Equestria Championships, Senior Division), she decided to send a commemorative solid gold pool cue: she had previously thought about a solid gold surfboard for the summer, but decided against it on the grounds gold doesn't float).
Anyway, her problem is this: the cue is a good solid two metres long exactly, but due to the Canterlot Post-Office's rather unreasonable health and safety policy, no package that exceeds one and a half metres in length, width or depth can be put through the regular parcel delivery service. What's more, as it's a present, she really doesn't feel like cutting the cue into smaller pieces, bending it, or otherwise damaging this frankly ludicrously expensive gift just to slip it past regulations.
Amazing what rich fillies do with their pocket money, am I right?
Anyway, your first problem (or puzzle) is to figure out how she can mail this gold ball-tapping stick through the mail without the post-pony getting on either of your cases. How?
