According to the Jam rules, Polyducks' title should be 'The Cave of Magic: Mushroom Hunt'.... hopefully, they're not magic mushrooms! :) Or they're magic mushrooms of the right type! :)
Ah, I see that including 'The Cave of Magic' is no longer one of the rules of the Jam. :)
There were complaints about the rule, and given that all entries will be tagged with the jam, it should be easy to discover entries without requiring a common prefix.
