You don't need to *win* the contest. Second place is good enough.
Horny needs a bit of motivation to win.
Gigi must be in the contest. If she is not, he probably won't win.
You will also need to cheat if you hope to beat Turbofrog.
Any spectacular performance will make the judges suspicious. If you cheat, they will test Horny.
But they won't test any of the other frogs.
