Well... that happened... (I was bored) Here is a very detailed guide on how to care for your Optimus Prime. Follow these instructions and he will grow.
The original audio is from Jenna Marble's How To Care For Your Cermet. Funny video right there XD I do not own the transformers... duh... they belong to Michael Bay's movies... and other things... So... I was bored and this happened. Wow. Enjoy!
