NËRP'S TOPICAL BAUBLE

Nërp has retaliated with another bauble!
He hasn't hung this one on the tree – instead he has produced instructions on how you can make such a bauble yourself.
Should you choose to construct this topical item, you will have an unusual and unique tree decoration – not to mention utterly bizarre!
The bauble depicts the Planet Nërptune, and will, according to Nërp at least, 'Beautify any Xmas Tree beyond all mere human expectation'.
I'll let him have this one, but then I'm going to put my foot down – impose a cease-fire…
