Anyone know what this gift box and cake IOU are about? OH WAIT! I think I just figured it out! We take the IOU to INU and she bakes us a cake! Now we finally know what she's babbling about.
INU: "akema akeca durfmadya noodle-head gibberbone!"
Translation: "Give me that coupon so I can bake you a cake!"
*runs off to Inu for free cake*
