Forum:RPS Triangle Game

Ever tried making a rock-paper-scissors style triangle out of Scribblenauts objects?

Try and think of 3 objects A, B, and C such that when put in a room in pairs, A would defeat B, B would defeat C, and C would defeat A.

I had 2 examples that apparently no longer work in the latest iOS Scribblenauts:
 * T-rex, Dingo, angry invulnerable baby
 * vampire, vampire hunter, T-rex

In older versions on iOS, any dingo would instantly kill any baby, and a vampire hunter could kill any vampire.

Can anyone find one that works?
