Opal, Agathe and Min discovered a mysterious bottle rolling about in a tide pool.
Opal used a handy bit of driftwood to prod the bottle towards the edge…
…and upon fishing it out, the girls discovered the top was firmly sealed with wax…
…and had what appeared to be a carefully folded piece of parchment stuck inside!
…the prize was carried in triumphant procession back to the Hitty cupboard for closer examination!
