As promised here is the re-post on how to make your very own, blood-thirsty, flesh-eating, MONSTER! 
To start off, take this starter monster: http://www.roblox.com/Starter-Monster-item?id=63840069
I’ll try to go into every little detail I can, I don’t usually do that but, this is a guide for Beginners!
- Open up Roblox Studio from the START menu on your computer, or from any other shortcut you have. Make sure it is ROBLOX Studio and NOT Play ROBLOX.
- Now insert the Model you just took.
- Now this is the real tutorial, pay close attention! Take a look at the “Zombie” you just inserted.
- Woo! You have a default Zombie , but maybe you want something more, something more interesting. Guess what? You can modify this puny zombie to become a real killer! :O
- For now leave “Health” and “Mode” as it is and move on to the “Robot” script. Open it up. (Yes it is not my script.. -.-)
Take a look at line 3
Got that? Hope so.
Moving on, after you have made any adjustments you want to the script, open up the script named “script” (lol at script named “Script”) under the “Robot” script.
Open the properties; Properties can be opened by going to the menu at the top left corner of ROBLOX studio. You can find it under “View”.
Now click “Zombie” with the tiny robloxian icon next to it.
Now, check its properties. You can change the Speed and Health from here! The monsters can catch you faster if its Walkspeed is higher than 17.
Now to change the name of your monster!
Change the color of it however you may like as well!
With a few modifications here and there, you might even start making monsters OUT OF THIS WORLD!
Hi-Tech Zombie: Super fast, and super powerful!
Lobster Zombie: May look huge but weaker than most zombies. Mutated Lobster Zombie: Super strong but, super slow!Note: Commenting would do you more good than pming on my ROBLOX account. I usually don’t read pms.
Thanks for reading and happy building!

I see no way to make that zombie into that hi-tech zombie you made
