How about purchasing a "Trademark" and LTD Co. to go with it, choose advertising etc as the market. It's only about £300 if I remember to do both.
Nice package, Domain Name(s), Trademark and setup Ltd Co? Perhaps even build a "Brand".
Just a thought, nice ring to it, agree it is highly brandable.
I'd guess lots of products could suit it. Kids Character etc.
Jingo the Jumbo Jet?
Get a neat "Jingo" logo, some illustrations done, Pay for some copy, publish on Amazon and iBooks? Facebook... Then Wait.
