(NB: Sorry. I haven't been able to upload this to the Google Play Store. This is what I got in reply: "After review, Whack the Minion, has been suspended and removed from Google Play as a policy strike because it violates the impersonation policy." Damn the minion. I should have chosen "google, the minion moron" instead...)
