Tru Ninja,
Fear not! Sea Lion bladder indeed....BAH! There is a meat fresh at hand that is well suited for your needs. We seek a meat that is resistant to random sleep, and for which care-free is the word of the day. A meat that is tender for lack of use. A meat that is endlessly marinated, soft and....oh, I can barely contain myself!
I hate to just give it away, so obvious is the answer...but you seek advice, and so I give.
Think man...think on this holiday of those most in need....those who's hands, no matter the hour of the day, are constantly alert, constantly thrust forth seeking your hard-earned dime. Those who give nothing in return but a bit of stink and a vile grimace if you pass them by.
Yes...yes...you are probably already catching on to my drift....it is the local homeless about whom I speak. A tireless bunch, seemingly unaffected by stress, a sleepless bunch willing to bother you no matter the time of day....and possessing of a meat which will empower you with their very own sleeplessness - a sleeplessness that will surely keep you awake for endless nights.
"Dear Mother! I have but a tasty new sausage for the stuffing..." you will say, presenting a ripe, plump sausage that, bonus to you, is stuffed within the very intestines of the one from whom this surprisingly tasty delicacy came. (I recommend at least an hour's soak in milk before use....trust me on this...)
A service to you - consuming the powerful flesh of the sleepless...and, of course, a service to the world. And yes, those canned goods you "donated" to the local shelter you can now return to the store for cost!! Win, win, win for you!
