Pacman in Minecraft

I have builded Pacman in vanilla Minecraft 1.7.

How it works:
It uses only one command:
/summon Ghast ~ ~2 ~ {Riding:{id:Zombie,ActiveEffects:[{Id:14,Ambient:1,Duration:2000000}]}}

This command is to summon this ghost. But not ghast. Its a ghost that doesn't flying, and follow you.

 

I think you shouldn't mine the pellets, but pick them up.
