Every game has some sort of super weapon for wholesale mayhem, starting with the BFG9000 in the original Doom to the torque bow in Gears Of War. While some games go for more interesting Easter eggs (like the elevator rave in Crysis 2) or just plain awesome (like how Left 4 Dead actually has a scene in Aperture Laboratories and the jukebox plays "Still Alive"), it's the rare talent that combines all three of these into one.
This is actually a double Easter egg, one that is interesting, and then the Triple Crown. At one point in exploring, you come across a shooting gallery with the cabbit from Tenchi Muyo. But if you look on the ground in front of it, you see Mr. Toots.
Yes. This My Little Pony is your super weapon.
It actually farts rainbows.
And they are strong enough to nuke anything in the game.
Oh, and if you do find Mr. Toots, it unlocks a special ending for the game.
Have a fun -- enjoy!
