So there is in fact another topic of this type, but I hesitate to necro something that's gone half a decade without a post. Sooo...
New types of summon contracts? Doesn't necessarily have to be for Naruto to use.
There could be a Seal contract, of course, if only to make puns with seals and sealing seals.
Of course, I would be partial to an Otter clan summons, as well. There's so much potential for punning ("Otter this world," "You otter write your will now", etc.), but the best part would be that THIS mofo would be the clan boss, blown up about a hundred times his original size to be on the size of Gamabunta.
