Building Effect [Model]

[Zzonehardy]

Hello, PoH (People of Hive)
I am working on a Nerubian Race, and I need a new building animation, I would like a giant hole to open in the ground and have the building start coming up from the ground. with the building dust from the Orc building animation...

I am not a modeler so I don't know if I can replace the building animation on existing model or not but if I can't...

The Egg Sack doodad,

And a 3 tier hive model,
Teir 1. couple eggs grouped together into one model,
Teir 2. eggs become purple and more are added,
Teir 3. a Giant Purple egg surrounded by little green eggs,

Team Color would be glorious!
