Imagine this all-knowing, all-supplying machine in the hands of a megalomaniacal psychopath. With a Mousekadoer, you would always -- with no effort on your end -- be as many steps ahead of your opponent as you need to be. Let's say an army approaches with tanks and rockets and fighter jets at the ready, because you've long since Toodle'd yourself to a nasty reputation. Simply summon the perky little guy, select "hydrodgen bomb," and watch gleefully as everybody within 10 miles immediately burns to a radioactive crisp.
Don't forget to select the Mystery Tool right after, which will absolutely be a hazmat suit because the Mousekadoer hath foretold the destruction and knows its master will require immediate protection.
All your gods are dead, and you'll never regain faith
The only limitation of a Mousekadoer is that Toodles doesn't pop in and tell you when it's "tool time," because free will. So it's on you to survive the enemy onslaught by your lonesome. Once you hit a roadblock and nothing in your arsenal will help you continue, then you summon Toodles. Select whatever you need to continue your humanicide, and if you didn't blow all your tools too early, you'll have billions of pitiful servants weeping under your thumb in no time.
