Neptune

All he needs is a trident and the likeness to Neptune would be complete.  He even has a hairpiece of bottle green stoneworts (Nitella sp.)

I think I can safely back blip this now that Brokenbanjo is a blipper no more.  He deleted his journal in disgust at the apparent takeover by Polaroid, and now there is a Mrs Brokenbanjo, he is far too preoccupied to bother with surfing the Blip ocean.  So it's unlikely he will spot this now, and Sheilwill is intrigued to know what he looks like.

We spent the day bobbing, snorkelling and wading about in Devoke Water, a large tarn that is a bit of an outlier to the main concentration of waterbodies in the Lake District.  Just another day's work.
