This highlights an important military application of Yukkuri. Before moving heavy artillery through an area, equip some shit-heads with sticks and tell 'em they'll get a cake for every un-easy metal saucer they whack-whack.
If it works, we should split the credit :) but sometimes things won't go as planned, the yukkuri can get lost, get easily distracted, be incompetent in spotting the mines, or think it will be a better idea to bring back the mine to mister human...
Anon: "Okay, remember, hit the mister saucers with mister stick and I'll give all of you some really easy sweet sweets!"
Yukkuris: "Yuyu! Okay easy! But remember to give very easy (Yukkuri's name) all of your sweet sweets! Lots is okay!"
Anon: "Yes, fine. But remember what I said, any uneasy yukkuris who poke mister saucer will take it easy forever! You're safe though, right?"
Yukkuris: "Of course we're easy! Can shitty mister human not tell? Wanna die?"
*Yukkuris go off eventually* *BLAM!* "Uneasy" yukkuri: "Yugi!!!!"
Other yukkuris: "Yu? That yukkuri must have been uneasy! Uneasy yukkuris deserve to die easy! Yu! A mister saucer! I'll get lots of easy sweet sweets if I hit you!"
