How about building a giant statue of yourself and your lovely buildings out of. Maybe with diamond eyes or a golden fly zipper, or something like that.
Then, build a giant creaper, fill it with dynamite, light the fuse, and shout as everything explodes "I KNOW YOUR GAME, MINECRAFT! I CAN DO IT BETTER! HA HA HA HA HA HA HA!!!!!"
Or how about making a big creeper statue out of tree leaves? Might be REALLY difficult, but It's
just about possible... I think.
How about a big sword made out of cacti? See, now you've got MY thoughts flowing! So... yeah, thanks for that, I guess.
