Oil Change ? Where's The Drain Plug ?!

[Astroboy]

It's located facing towards the right.

I think I found it, if it is what I think it is.

Where as in the above pic, the drain is facing the rear, my drain (I believe) is facing to the right.

My logic is that it has to be the big bolt located around the lowest point of the oil pan, although it almost looks like one of the ordinary bolts which fasten the engine...

It is within easy reach without removing the skid plate.
