HeartGold- Its entire body is shielded by a steel-hard shell. What
lurks inside this shell is a total mystery.

I'm wondering what's in it's shell, has it been revealed

Notice the total mystery part
^ oh the troll xD
Maybe it's pizza.
its obviously a little pinecone
Who knows? Maybe internal organs.

This was all I could find.

With the exception of the eyes and possibly the spikes, it is unknown
what Forretress look like beneath the armor.

So,it is still a mystery and gamefreak hasn't revealed anything about it.

The Pokedex can actually be very misleading at times, like on
Weezing's page it explains that triplets have been found, though not
legitimately obtainable; untrue-Fizzcube.

Sorry if i couldn't help you.This was all i could find.
