"Interacting with Creepers" is my first, and proper animation on blender, It was a really fun project for me to do, It took a few hours to make it, but I think it was worth it
You can watch it in 720p or even better.. 1080p.

The guy is trying to break the tree, but he is pushing it.... Noob! Anyway he falls on his face and decides to give up, he is then approached by a creeper that was a spectator watching him fail... The creeper creeps on him until he reaches the edge of the terrain then the Creeper whacks him off.
